Nevertheless, Low Noise Factory has succeeded in making its extremely low-noise microwave amplifiers. Today, they are the first choice in both radio telescopes and quantum computers.</b></p><div><span style="background-color:initial">Both the E6 and Västkustbanan sweep close to the office building in Kallebäck. Nevertheless, no traffic noise is considered on the thirteenth floor, where Low Noise Factory is located. Instead, here is another kind of noise in the center. Namely, the inevitable signal noise that occurs in all electronics, including the random movements of the electrons in semiconductors.</span><br /></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/lownoisefactory_I0A5271_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />In the company's transistor-based amplifiers, this noise is reduced to an absolute minimum. How?</div> <div>Well, you benefit from phenomena that only occur on a nano-scale, with exotic materials such as indium phosphide and - in most cases - through cryogenic use. That is, cooling to a few degrees above absolute zero.</div> <div>&quot;The vast majority of applications do not benefit from such a low noise. It is fine with something worse and cheaper&quot;, explains the company's founder and principal owner Niklas Wadefalk (to the right).</div> <div>One exception is the radio astronomy, which is trying to capture extremely weak signals from space.</div> <div>&quot;It is usually said that the sensitivity of a radio telescope is equal to the capture area divided by the system noise. This means that the sensitivity can be improved either by larger antennas, which can cost millions, or by less noise in the amplifier&quot;, explains Niklas Wadefalk and adds that the latter becomes considerably cheaper.</div> <div><br /></div> <div>It was precisely to meet the demanding radio astronomers' needs that he started the company thirteen years ago. He had previously worked for a few years as a research engineer at Chalmers and learned to build cryo-amplifiers. Such amplifiers had long been an important research area at Chalmers, driven by recurring assignments to build single-piece amplifiers for different space projects, including for the Odin satellite. Then Niklas Wadefalk was attracted to the Caltech University in California, where for five years he further developed the design of the cryo amplifier. During these years the radio astronomy changed. Gradually, they began to plan future telescopes in the form of many, small scattered antennas instead of single large ones.</div> <div>&quot;Hence, hundreds, perhaps thousands of low noise amplifiers would be needed, something that universities and research institutions would hardly be able to produce themselves. I saw a niche for a commercial and serious company that could provide guarantees and ensure continuity.&quot;</div> <div>He decided to move home to Gothenburg and Chalmers again, while he started Low Noise Factory alongside. Bit at first, it wasn't so much of a factory. The company's first amplifier, Niklas Wadefalk manufactured in his own bedroom. But graduallt, orders rolled in.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/lownoisefactory_I0A5159_amplifier_665x330.jpg" alt="Picture of amplifier." style="margin:5px" /><br /><em>Inside the Low Noise Factory's best-selling amplifier, popular in both quantum research and radio astronomy.</em><br /><br /></div> <div>Since the core component itself, the half-millimeter-sized transistors, was processed in Chalmers cleanroom, a steep learning curve was also initiated in production technology at Chalmers. At the start, a few hundred transistors were manufactured on centimeter-sized pieces of indium phosphide.</div> <div>&quot;Today, 50,000 transistors can be placed on a &quot;wafer&quot; large as a CD. It has been an avalanche development thanks to all the feedback between us and Chalmers.&quot;</div> <div>Another big change is that many amplifiers are now made in the form of an integrated circuit, which minimizes the need for manual mounting work on the microscope.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/lownoisefactory_I0A5142_pincett_665x330.jpg" alt="Pincette on wafer." style="margin:5px" /><br /><em>With a pincette, one of the fifty thousand transistors from the &quot;wafer&quot; manufactured in Chalmers clean room is picked to become a core component of a new amplifier.</em><br /><br /></div> <div>Low Noise Factory is today, with its nine employees, almost alone in the world to manufacture cryogenic amplifiers for the very highest low noise requirements.</div> <div>The production rate is now up to a thousand units per year. But the radio astronomers are not behind the recent increase in order intake. Instead, the orders come from the many universities and IT companies that are competing to create the first useful quantum computer.</div> <div>&quot;It is a large and growing market for us, but it also means new and higher demands.&quot;</div> <div>One demand applies to the heat development of the amplifiers. Quantum computer scientists think that 4 kelvin is too hot, they prefer to go down in millikelvin.</div> <div>&quot;It is not certain that it is possible to use transistor amplifiers for this, but we are researching with Chalmers to get further.&quot;</div> <div>It will probably be in the form of the same kind of tangible experimentation that has so far yielded results. According to Niklas Wadefalk, there is no exclusive theoretical knowledge or &quot;business secret&quot; that lies behind the company's dominance within its niche.</div> <div>&quot;There is some feature of our transistors that makes them better than any other at cryogenic temperatures. Something we have come up with through a lot of trial-and-error. But exactly what, we don't actually know.&quot;</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">Text: Björn Forsman</span><br /></div> <div>Photo: Anna-Lena Lundqvist</div> <div><br /></div> <div>Previously published in Chalmers magasin, no. 2, 2018.</div>Thu, 17 Jan 2019 09:00:00 +0100https://www.chalmers.se/en/departments/mc2/news/Pages/New-head-of-the-Photonics-Laboratory.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/New-head-of-the-Photonics-Laboratory.aspxNew head of the Photonics Laboratory<p><b>​Peter Andrekson, professor of photonics, is new head of the Photonics Laboratory at MC2 since 1 January 2019. &quot;It doesn&#39;t really feel that dramatic,&quot; he says.</b></p><div><span style="background-color:initial">Peter Andrekson looks with confidence on his new appointment. He succeeds the laboratorie's long-standing head Anders Larsson:</span><br /></div> <div>&quot;Anders has &quot;raked the way&quot; in an exemplary manner for about 25 years. Over the years, I have also been involved in many decisions at different levels, and for example, was a member of Chalmers' board for seven years, so this does not feel dramatic for me,&quot; says Andrekson.</div> <div><br /></div> <div><strong>Do you have any specific thoughts about what you want to do as head?</strong></div> <div>&quot;Chalmers annual management day next week deals with, among other things, the managers' limited opportunity for recovery. Here I have two thoughts: thank no to things if they are not important and never hesitate to delegate tasks to others. I'm going to keep doing that.&quot;</div> <div><br /></div> <div>As laboratory head, Andrekson wants to further develop the photonics research, and make it more visible to the students at Chalmers:</div> <div>&quot;Photonics is a very wide area with ​​applications almost everywhere in our society. We received great feedback on our research in the external review of MC2 last year. But now we need to think more visionary about which application areas we want to look more closely at over the next ten years, and then preferably with great synergy linked to our current research. We also need to become more visible to the students at the graduate level at Chalmers in various ways,&quot; he says.</div> <div><br /></div> <div>Peter Andrekson was born in 1960 and defended his PhD at Chalmers in 1988. He has been awarded several awards for his work. From 1989 to 1992, he spent his time at AT&amp;T Bell Laboratories in the United States, but returned to Chalmers after that and has been working here since then.</div> <div>&quot;My research is mostly about optical fiber communication with high performance, both in terms of capacity and energy consumption, but also on a special type of extremely low noise optical amplifier that can prove useful for, among other things, communication in &quot;deep space&quot; over millions of kilometers. The latter work is supported by a ten-year VR project, which enables greater risk taking, something I appreciate a lot,&quot; he says.</div> <div><br /></div> <div>In parallel with the new assignment, Peter Andrekson will continue as director of the research center FORCE, which he has led since the start in 2010. The acronym stands for Fiber Optic Communications Research Centre.</div> <div><br /></div> <div>Another current change among the heads of MC2 is that Dag Winkler, professor of physics and former head of department at the department, is the new head of the Quantum Device Physics Laboratory since 1 September 2018. He then succeeded August Yurgens.</div> <div><br /></div> <div>Text: Michael Nystås</div> <div>Photo: Henrik Sandsjö</div>Thu, 10 Jan 2019 09:00:00 +0100https://www.chalmers.se/en/departments/mc2/news/Pages/MC2-researcher-gets-major-grant-from-The-Swedish-Research-Council.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/MC2-researcher-gets-major-grant-from-The-Swedish-Research-Council.aspxMC2 researcher gets major grant from The Swedish Research Council<p><b>​Åsa Haglund, professor at the Photonics Laboratory at MC2, has been awarded a consolidator grant from The Swedish Research Council (VR). She is funded with 10,4 million SEK for the years 2019-2024. &quot;I had to restrain myself from jumping for joy. It is really a dream come true&quot;, says Åsa Haglund.</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/MC2/News/asa_haglund_170112_hsandsjo_350px.jpg" alt="Picture of Åsa Haglund." class="chalmersPosition-FloatRight" style="margin:5px" />She tells us that she was sitting on the train to Stockholm when she got the announcement.</span><br /></div> <div>&quot;It feels fantastic! Doing the transition from a young researcher to an established professor is a very important step in one’s academic career, but also a big challenge. This generous consolidator grant will be the key enabler to make this happen&quot;, Åsa Haglund continues.</div> <div><br /></div> <div>The grant is funding her project &quot;Ultraviolet and blue microcavity lasers&quot;, and will strengthen Åsa Haglund's group and help them establish a creative research environment. </div> <div>&quot;We can now have a long-term perspective that you seldom get with normal grants. We will dare to invest in more high-risk, high-gain research that hopefully will pay off in the end.&quot;</div> <div><br /></div> <div>The project aims to develop the very first electrically driven ultraviolet microcavity laser. Åsa Haglund and her colleagues will make blue microcavity lasers useful for real-world applications by trying to bring the power conversion efficiency above the single digit range.</div> <div>&quot;When these devices are realized, they will be of great use for a myriad of applications such as solid-state lighting, water purification, photolithography, biomedical applications, enhancing health-promoting substances in plants, gas sensing, fluorescence-based sensing and UV curing&quot;, she explains and continues:</div> <div>&quot;The project will get a flying start with two recent breakthroughs by our group; measures against optical anti-guiding and a selective etch technique. The latter will also be a key enabler in many other areas besides microcavity lasers where airgaps or substrate removal is crucial, such as for high-efficiency UV-LEDs.&quot;</div> <div><br /></div> <div>The grant will also fund a post-doc and a PhD student; an important strengthening of the research group. </div> <div>&quot;We have many challenges ahead of us, but we will do our best to turn our dream of microcavity lasers emitting in the blue and ultraviolet into reality&quot;, says Åsa Haglund.</div> <div><br /></div> <div>She has long Chalmers experience, and got her PhD degree already in 2005, working for Professor Anders Larsson, then head of the Photonics Laboratory, where she has stayed since then.</div> <div>&quot;I focused on improving the performance of infrared-emitting vertical-cavity surface-emitting lasers (VCSELs). The method we developed to boost the single-mode output power in these devices caught a lot of attention and is now used by many VCSEL companies across the world.&quot; </div> <div><br /></div> <div>Åsa Haglund is one of the most talented and successful young researchers at MC2. In 2012 she was able to start her own group when she was awarded with a young researcher grant from The Swedish Research Council. The group focused on developing microcavity lasers in GaN-based materials to achieve emission in the blue.</div> <div>&quot;We could strongly benefit from the device knowledge we have acquired over the years on VCSELs. At the same time we had to start from scratch, since many of the concepts used for infrared VCSELs in GaAs-based materials can’t be translated to blue-emitting GaN-based devices&quot;, says Åsa Haglund.</div> <div><br /></div> <div>As a researcher it is important to have good networks with other researchers to interact with and share knowledge and experience with. She recalls when she first visited a GaN-based conference:</div> <div>&quot;Out of 900 participants, I only recognized one person. It has taken a few years to build up a network in a community I was completely unknown to. Now we have strong collaborations with some of the best material’s groups in the world. This, together with the dedication from our skilled group members, puts us in a unique position to make state-of-the-art devices. Something I am very thankful for.&quot;</div> <div><br /></div> <div>The purpose of a consolidator grant is to give the most prominent junior researchers the opportunity to consolidate their research and broaden their activities as independent researchers. Three researchers at Chalmers received funding in this round. Beside Åsa Haglund, also Christoph Langhammer and Ermin Malic at the Department of Physics were awarded. The total grant amount for 2019-2024 is almost 221,5 million SEK. Chalmers gets 33,4 million SEK. 306 researcher from all over Sweden applied for a grant. Only 20 were successful; seven women and 13 men.</div> <div><br /></div> <div>Text: Michael Nystås</div> <div>Photo: Henrik Sandsjö</div> <div><br /></div> <div><strong>Read more about the consolidator grants and the decision &gt;&gt;&gt;</strong></div> <div><a href="https://www.vr.se/english/calls-and-decisions/calls/calls/2018-06-07-consolidator-grant.html">www.vr.se/english/calls-and-decisions/calls/calls/2018-06-07-consolidator-grant.html</a></div> <div><br /></div> <div><a href="https://www.vr.se/english/calls-and-decisions/grant-decisions/decisions/2018-09-06-consolidator-grant.html">www.vr.se/english/calls-and-decisions/grant-decisions/decisions/2018-09-06-consolidator-grant.html​​</a></div>Thu, 06 Dec 2018 11:00:00 +0100https://www.chalmers.se/en/departments/mc2/news/Pages/Popular-professor-celebrated-on-his-80th-birthday.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/Popular-professor-celebrated-on-his-80th-birthday.aspxPopular professor celebrated on his 80th birthday<p><b>​Many people wanted to celebrate the 80th anniversary of the MC2 professor Tord Claeson.

Susannah Carlsson, communications officer at the department, had laid down her heart to make everything practical work around. Cake, coffee and non-alcoholic bubbles were served under undemanding and simple conditions, according to Tord Claeson's wish. The head of MC2, Professor Mikael Fogelström, welcomed everyone and took initiative to today's first, but not last, &quot;Happy Birthday&quot;.</span><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/tc_donats_erts_IMG_6320_665x330.jpg" alt="Picture from the celebration of Tord Claeson." style="margin:5px" /><br /><span style="background-color:initial">Some guests had traveled a long way to come and celebrate him. Dr Donats Erts (above) came from the University of Latvia, where he is the director of the Institute of Chemical Physics.</span><br /></div> <div>&quot;I started working together with Tord and his group in 1992, and have come here just to celebrate him. And to take the opprotunity to work a bit&quot;, he says in a break.</div> <div>Donats Erts handed over a bag of souvenirs from the university, and also had a personal greeting from the president Indrikis Muiznieks with him.</div> <div><br /></div> <div>Another guest from far away was Victor Petrashov, Professor at the University of London. He has known Tord Claeson since 1985, and had an active role in the planning for the new MC2 department and the cleanroom in the 90s.</div> <div>&quot;I had the privilege of being involved in that work. With MC2 as a model I have since been able to build similar environments in both Russia and the UK. Tord is really a model that has kept calm and kept on&quot;, says Victor Petrashov, when we have a small chat with him.</div> <div><br /></div> <div>Several of Tord Claeson's former PhD students, among them the MC2 professors Per Delsing and Dag Winkler, as well as Staffan Rudner, and professors Maj Hanson, Eva Olsson, Mats Jonson and David Haviland at KTH held very beautiful speeches, where they did not save on the gun.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/tc_justin_micke_dag_august_IMG_6364_665x330.jpg" alt="Picture from the celebration of Tord Claeson." style="margin:5px" /><br /><em>Justin Schneiderman, Mikael Fogelström, Dag Winkler and August Yurgens were among the congratulators.

You really are the father of our laboratory&quot;, he said.</div> <div><br /></div> <div>David Haviland, professor of nanostructural physics at KTH Royal Institute of Technology, spoke of Tord Claeson as an inspiration also for foreign researchers, like himself.</div> <div>&quot;I came here as a postdoctoral student a dark and rainy November in 1989. Tord and his wife Madeleine met me at the train station and helped me to the apartment where I was going to live. I and other international researchers owe Tord our gratitude. As a professor, I can also see how difficult it is to offer a research environment like Tord Claeson's&quot;, said David Haviland.</div> <div><br /></div> <div>Maj Hanson, professor of physics at Chalmers, highlighted Tord Claeson's personal &quot;anti-authoritarian&quot; leadership style:</div> <div>&quot;I have known him for almost 50 years. Often we have been led by authoritarian people who have never been able to build the creative environments that Tord has done. He has left a lot of decisions to his employees and by that opened up their creativity. He is a generous person who spreads light and warmth wherever he comes&quot;, she said before encouraging everyone to sing &quot;Happy Birthday&quot; in Swedish, followed by three cheers.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/tc_publik_b_IMG_6230_665x330.jpg" alt="Picture from the celebration of Tord Claeson." style="margin:5px" /><br /><span style="background-color:initial">Per Delsing, professor and head of the Quantum Technology Laboratory, said jokingly that the only thing Tord Claeson has not understood is the meaning of retirement.</span><br /></div> <div>&quot;I'm really impressed that you're still going to work every day and keeping you up to date about the research. You regularly email me new scientific articles that you think I have already seen, which I do not have...&quot;</div> <div>Delsing also recounted a number of prestigious assignments and prizes that Tord Claeson has received over the years, and deemed he was the one who took the research in low temperature physics and superconductivity to Chalmers.</div> <div>&quot;Today we can really see how the area has grown thanks to Tord. He started with electron beam lithography and built up the first nano lab that, together with others, became the current Nanofabrication Laboratory. Without Tord, I do not think we have had any cleanroom. This building had also not existed&quot;, said Per Delsing.</div> <div>He also celebrated the strong, friendly and curious research environment that Tord Claeson built up over the years.</div> <div><br /></div> <div>Staffan Rudner was one of Tord Claeson's first PhD students and began in 1975.</div> <div>&quot;Tord has been a very inspiring person to work with. He has shaped my own life in a way&quot;, said Staffan Rudner.</div> <div>He told the audience, among other things, a memorable conference trip they did together to Grenoble in 1979.</div> <div>&quot;Tord has always been very frugal, so we traveled in his not completely new car all the way from Gothenburg to Grenoble. Tord brought a thick book with the lowest prices for accommodation. It was our guide! When the car's brakes broke down, Tord showed up his best experimental side and managed to repair the car so we could move on&quot;, said Staffan Rudner.</div> <div><br /></div> <div>Dag Winkler also mentioned Tord Claeson's frugal sense of mind, telling that on a conference trip to Kyoto, he chose to spend the nights in a monastery to save money for the hotel.</div> <div>&quot;Bit when Tord realized that he would be woken for morning prayers at 5 o'clock, he resigned and checked into the hotel like us others,&quot; said Dag Winkler.</div> <div><br /></div> <div>The jubilee's economical restraint was a recurring theme during the celebration, to the audience's delight. Mats Jonson, professor of condensed matter physics at Chalmers, had Tord Claeson as a teacher.</div> <div>&quot;I have learned many things from Tord, not least to be economical when traveling. In Brussels, for example, we took the bus to the meeting while everyone else went by taxi. In Kyoto we carried our suitcases to the hotel, because Tord insisted it was only two kilometers walk from the train station&quot;, Mats Jonson told us.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/tc_evaolsson_majhanson_staffan_tord_IMG_6289_665x330.jpg" alt="Picture from the celebration of Tord Claeson." style="margin:5px" /><br /><span style="background-color:initial">Eva Olsson (above), professor of physics at Chalmers, met Tord Claeson when she was a PhD student.

I appreciate our friendship high&quot;, she said.</div> <div><br /></div> <div>Tord Claeson himself occasionally squirmed discreetly over the many kind words, but was of course both happy and honored:</div> <div>&quot;An old doctoral student once asked me for guidance. I said 'then you should not believe a word of what professors say'. So don't take this too seriously either&quot;, he commented joyfully when he thanked everyone for taking the time to come.</div> <div>He himself thinks he has been lucky, both privately and professionally, and managed to be in the right place at the right time, and surrounded by the right people:</div> <div>&quot;I have had the good fortune to end up in good research groups, where there were good colleagues to cooperate with. I do not think I've been so much of a supervisor; my PhD students have found their own subjects. They have really developed and are located both here at Chalmers and all over the world.

They have discovered a novel method to dope graphene over large areas that enables the study of the physics at the Dirac point, where graphene is charge neutral and electron transport studies are not obscured by mesoscopic effects and charge disorder. The unorthodox method utilizes polymers to assist the assembly of acceptor molecules on graphene. The results were recently published in Nature Communications.</b></p><div><span style="background-color:initial">A well-established technology to produce high quality graphene is by heating up silicon carbide (SiC) in the presence of inert Argon gas. Under proper growth conditions, this technique results in so-called epitaxial single layer graphene on the surface of silicon carbide (epigraphene). Compared to graphene grown by other methods, epigraphene grows as a single crystal over the entire silicon carbide substrate, anticipating higher electronic quality with respect to polycrystalline graphene grown by other methods. However, on SiC, the graphene layer interacts very strongly with the substrate resulting in very large transfer of electrons from SiC into the graphene layer. To fully explore and exploit the properties of graphene requires the capability to tune the amount of electrons transferred from the substrate. For epigraphene, the very strong interaction between the graphene layer and SiC substrate makes is difficult control at will the amount of electron transfer (i.e. doping). The inability to finely dope epigraphene has been a major challenge in studying and exploiting the properties of this promising material.</span><br /></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/Samuel_Lara_Avila_1_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />The scientists have discovered a novel method to carefully assemble molecules on the surface of epigraphene to dope it with unprecedentedly high control, while keeping intact its electronic quality. The method utilizes polymers to assist the assembly of electron-accepting molecules (i.e. dopants) on the surface of graphene; once in contact with graphene, dopant molecules withdraw electron from graphene and this interaction keeps molecule in place. To achieve this, polymers are mixed with dopant molecules, and this blend is then deposited on the epigraphene substrate by simple spin-coating, which is a standard and scalable microfabrication step performed in ambient conditions. </div> <div><br /></div> <div>“By carefully choosing the polymer, the molecular dopant and the substrate, we have obtained rather exciting results. With a simple spin-coating step, which is routine work in cleanroom environment, we can heal epitaxial graphene and produce a centimeter-scale Dirac material with very high electronic quality. The electronic disorder that we measure in the resulting doped graphene is lower than that of microscopic graphene flakes encapsulated by hexagonal Boron Nitride (hBN), which is the method that thus far results in the highest quality graphene”, says Samuel Lara-Avila (above picture), Assistant Professor at the Quantum Device Physics Laboratory at the Department of Microtechnology and Nanoscience – MC2, at Chalmers. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/sergey_kubatkin_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“This is a very unusual example of a highly uniform system that arises from the combination of “dirty” elements: epitaxial graphene is regarded as a lower quality material compared to exfoliated graphene flakes, and both dopants and polymers are known to deteriorate the electronic qualities of graphene. But the combination yields high mobility epigraphene, doped to the Dirac point with high uniformity over macroscopic scale”, adds Sergey Kubatkin (to the right), Professor in the same lab.</div> <div><br /></div> <div>The researchers used a combination of the common polymer poly methyl methacrylate (PMMA) and the well-known F4TCNQ acceptor molecule to form the dopant blend. They discovered that when the dopant blend is deposited on epigraphene, molecular dopants (i.e. F4TCNQ) diffuse through the polymer and spontaneously assemble at the epigraphene-polymer interface, making a densely packed layer of 3-4 molecules per square nanometer. Surprisingly, this dense assembly of molecules results in epigraphene doped close to the Dirac point with an exceptionally small amount of charge inhomogeneity, i.e. disorder. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/hans_he_181119_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Using epigraphene, these results simultaneously show the potency of this method, because epitaxial graphene grown on SiC is particularly difficult to dope while at the same time maintaining its electronic quality.</div> <div>“We have made a significant progress in approaching a largely unexplored realm of graphene research – a study of delicate fascinating physical properties of macroscopic graphene samples doped at the Dirac point, in which electron transport measurements are not obscured by size-induced mesoscopic effects and charge puddles, typical of microscopic samples”, says Hans He (to the right), PhD student in the group. </div> <div><br /></div> <div>This method can be the key to explore and exploit the fascinating physical properties of epigraphene and other related Dirac materials. While there exist world-wide efforts to synthesize high quality materials, unintentional impurities or hard-to-reach stoichiometry during material growth result in heavily doped crystals. In this situation, at high doping levels, the interesting physics of Dirac materials might be obscured or entirely absent. A few other examples of novel physical effects expected – made possible by the new results – include study of metal-insulator transitions, interacting Dirac fermions, Wigner crystallization, possibility to observe Zitterbewegung of electrons in Dirac materials, and specular Andreev reflections among others.</div> <div>“The resulting doped epigraphene is also of technological relevance, and the material is readily applicable in quantum resistance metrology, light sensors and magnetic sensors. But the molecular assembly method can open other research avenues by using a different combination of polymer/dopants, and also when applied to other atomically thin materials”, concludes Samuel Lara- Avila. </div> <div><br /></div> <div>The research, at the border between polymer chemistry and solid state physics, was a collaborative effort between groups at the Department of Microtechnology and Nanoscience – MC2 – and the Department of Chemistry and Chemistry Engineering at Chalmers.

Now, researchers from Chalmers University of Technology, Sweden, present a totally new way to clean contaminated water, through an electrochemical process. The results are published in the scientific journal Nature Communications. ​​​</b></p><div><span style="background-color:initial">“Our results have really exceeded the expectations we had when we started with the technique,” says the research leader Björn Wickman, from Chalmers’ Department of Physics. “Our new method makes it possible to reduce the mercury content in a liquid by more than 99%. This can bring the water well within the margins for safe human consumption.” </span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div>According to the World Health Organisation (WHO), mercury is one the most harmful substances for human health. It can influence the nervous system, the development of the brain, and more. It is particularly harmful for children and can also be transmitted from a mother to a child during pregnancy. Furthermore, mercury spreads very easily through nature, and can enter the food chain. Freshwater fish, for example, often contain high levels of mercury. </div> <div><br /></div> <div>In the last two years, Björn Wickman and Cristian Tunsu, researcher at the Department of Chemistry and Chemical Engineering at Chalmers, have studied an electrochemical process for cleaning mercury from water. Their method works via extracting the heavy metal ions from water by encouraging them to form an alloy with another metal. </div> <div><br /></div> <div>“Today, removing low, yet harmful, levels of mercury from large amounts of water is a major challenge. Industries need better methods to reduce the risk of mercury being released in nature,” says Björn Wickman. </div> <div><br /></div> <img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Vattenrening_labbsetup1_webb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;background-color:initial" /><div>Their new method involves a metal plate – an electrode – that binds specific heavy metals to it. The electrode is made of the noble metal platinum, and through an electrochemical process it draws the toxic mercury out of the water to form an alloy of the two. In this way, the water is cleaned of the mercury contamination. The alloy formed by the two metals is very stable, so there is no risk of the mercury re-entering the water. </div> <div><br /></div> <div>“An alloy of this type has been made before, but with a totally different purpose in mind. This is the first time the technique with electrochemical alloying has been used for decontamination purposes,” says Cristian Tunsu.</div> <div><br /></div> <div>One strength of the new cleaning technique is that the electrode has a very high capacity. Each platinum atom can bond with four mercury atoms. Furthermore, the mercury atoms do not only bond on the surface, but also penetrate deeper into the material, creating thick layers. This means the electrode can be used for a long time. After use, it can be emptied in a controlled way. Thereby, the electrode can be recycled, and the mercury disposed of in a safe way. A further positive for this process is that it is very energy efficient.</div> <div><br /></div> <div>“Another great thing with our technique is that it is very selective. Even though there may be many different types of substance in the water, it just removes the mercury. Therefore, the electrode doesn’t waste capacity by unnecessarily taking away harmless substances from the water,” says Björn Wickman. </div> <div><br /></div> <div>Patenting for the new method is being sought, and in order to commercialise the discovery, the company Atium has been setup. The new innovation has already been bestowed with a number of prizes and awards, both in Sweden and internationally. The research and the colleagues in the company have also had a strong response from industry. ​ </div> <div><br /></div> <div>“We have already had positive interactions with a number of interested parties, who are keen to test the method. Right now, we are working on a prototype which can be tested outside the lab under real-world conditions.”</div> <div><br /></div> <div>Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a> </div> <div>and Joshua Worth, <a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se ​</a><br /></div> <div><br /></div> <div>Read the article, <a href="https://www.nature.com/articles/s41467-018-07300-z">“Effective removal of mercury from aqueous streams via electrochemical alloy formation on platinum”​</a> in Nature Communications.</div> <div><br /></div> <div><div><a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/removing-toxic-mercury-from-contaminated-water-2800540"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release and download high-resolution images. ​​</a><span style="background-color:initial">​</span></div></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Vattenrening_Bjorn_Wickman_Cristian_Tunsu_portratt_750x340_NY.jpg" alt="" style="margin:5px" />​<span style="background-color:initial">Björn Wickman and Cristian Tunsu</span><span style="background-color:initial"> ​are pr</span><span style="background-color:initial">esenting a new and effective way of cleaning mercury from water.

He will tell the story about the fascinating journey which led to a groundbreaking underground discovery - and to the Nobel Prize in Physics 2015. ​</b></p><div><span style="background-color:initial"><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/F/350x305/1_Takaaki_Kajita_350x305.jpg" alt="" style="margin:5px;width:320px;height:281px" />What he and Arthur B. McDonald had discovered was oscillations of elusive particles called neutrinos. In the Japanese underground observatory Kamiokande the research group led by Kajita could register the oscillations which showed that the particles, assumed to be massless, actually have mass. The discovery has had profound implications on for example stellar structure and cosmology. <br /></span><br /></div> <div>“Neutrinos are extremely fascinating particles, the second most common (after photons) in the Universe but so elusive that we have a hard time noticing their presence. They are potentially the key to understand some of the deepest questions that still remain unsolved,” says Professor Thomas Nilsson, experimental physicist and Head of the Department of Physics at Chalmers. <br /><br /></div> <div>Neutrinos were created at the birth of the Universe. Today they are created in nuclear processes – in the Cosmos, in our laboratories and in nuclear reactors.<br /><br /></div> <div>“When I joined Kamiokande, underground experiments were just a very small sub-field of particle physics experiments. At present, after more than 30 years, these underground experiments have become some of the most promising, powerful, versatile, and efficient ways to explore both particle physics and the Universe itself. This research underground continues to stimulate my interest. I look forward to what new discoveries the future will hold,” writes Professor Takaaki Kajita in The Nobel Prizes 2015, published on behalf of The Nobel Foundation. <br /><br /></div> <div>At Chalmers, many researchers are looking forward to Professor Kajita’s visit, especially physicists within astro, particle and subatomic physics. <br /><br /></div> <div> “I’m very glad for this event for several reasons. I studied particle physics as a student, but ended up as a reactor physicist, which is a completely different area. Nevertheless, both the existence of neutrinos, as well as two out of the three possible neutrino oscillations were proven by using neutrinos from nuclear reactors,” says Professor Imre Pázsit at the Department of Physics at Chalmers.<br /><br /></div> <div>Due to this fact, and to his extensive collaboration with Japanese physicists, Pázsit got into contact with the neutrino research quite some time ago. He met Professor Kajita in Stockholm in connection to the Nobel ceremony and at the Nobel Dialogue Dinner in Tokyo last year they met again.  <br /><br /></div> <div>“There I understood his interest to visit Sweden again, which of course helped to invite him to Chalmers. I look forward to his lecture and I hope that many will take the opportunity to listen to a fascinating talk,” says Professor Pázsit.</div> <div>Imre Pázsit has collaborated with Japanese researchers for more than 25 years. In 2016 he was awarded the Order of the Rising Sun for his &quot;Contribution to the promotion of scientific and technological exchanges and mutual understanding between Japan and Sweden&quot;.<br /><br /></div> <div>Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmer.se</a></div> <div>Image credit: Bengt Nyman, Wikimedia commons</div> <div><br />The lecture by Professor Takaaki Kajita will be open to the public, free of charge and held in Gustaf Dalén lecture hall at Chalmers campus Johanneberg, Gothenburg on 28 November at 15.15-16.00.<br /></div> <div>No registration is needed. <br /></div> <div><a href="http://graphene-flagship.eu/" style="outline:currentcolor none 0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a> <a href="/en/departments/physics/calendar/Pages/General-Physics-Colloquium_181129.aspx">Read more about the event and add it to your calendar</a><br /></div> <div> </div> <h4 class="chalmersElement-H4">The Nobel Prize in Physics for 2015: Metamorphosis in the particle world</h4> <div>The Nobel Prize in Physics 2015 recognises <strong>Takaaki Kajita</strong> in Japan and <strong>Arthur B.
