Now, researchers at Chalmers University of Technology, Sweden, and Regensburg University in Germany have shed light on the ultrafast dynamics in these novel materials. The results were recently published in the prestigious journal Nature Materials.​​​</b></p><div><div>Imagine you are building an energy-efficient and super-thin solar cell. You have one material that conducts current and another that absorbs light. You must therefore use both materials to achieve the desired properties, and the result may not be as thin as you hoped.</div> <div><br /></div> <div>Now imagine instead that you have atomically thin layers of each material, that you place on top of each other. You twist one layer towards the other a certain amount, and suddenly a new connection is formed, with special energy states – known as interlayer excitons – that exist in both layers. You now have your desired material at an atomically thin level.</div> <div><br /></div> <div>Ermin Malic, researcher at Chalmers University of Technology, in collaboration with German research colleagues around Rupert Huber at Regensburg University, has now succeeded in showing how fast these states are formed and how they can be tuned through twisting angles. Stacking and twisting atomically thin materials like Lego bricks, into new materials known as ‘heterostructures’, is an area of research that is still at its beginning.</div></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/ErminMalic_190415_05_350xwebb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><div>“These heterostructures have tremendous potential, as we can design tailor-made materials. The technology could be used in solar cells, flexible electronics, and even possibly in quantum computers in the future,” says Ermin Malic, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div>Ermin Malic and his doctoral students Simon Ovesen and Samuel Brem recently collaborated with researchers at Regensburg University. The Swedish group has been responsible for the theoretical part of the project, while the German researchers conducted the experiments. For the first time, with the help of unique methods, they succeeded in revealing the secrets behind the ultrafast formation and dynamics of interlayer excitons in heterostructure materials. They used two different lasers to follow the sequence of events. By twisting atomically thin materials towards each other, they have demonstrated that it is possible to control how quickly the exciton dynamics occurs.</div> <div><br /></div> <div>“This emerging field of research is equally fascinating and interesting for academia as it is for industry,” says Ermin Malic. He leads the Chalmers Graphene Centre, which gathers research, education and innovation around graphene, other atomically thin materials and heterostructures under one common umbrella.</div> <div><br /></div> <div>These kinds of promising materials are known as two-dimensional (2D) materials, as they only consist of an atomically thin layer. Due to their remarkable properties, they are considered to have great potential in various fields of technology. Graphene, consisting of a single layer of carbon atoms, is the best-known example. It is starting to be applied in industry, for example in super-fast and highly sensitive detectors, flexible electronic devices and multifunctional materials in  automotive, aerospace and packaging industries.</div> <div><br /></div> <div>But graphene is just one of many 2D materials that could be of great benefit to our society. There is currently a lot of discussion about heterostructures consisting of graphene combined with other 2D materials. In just a short time, research on heterostructures has made great advances, and the journal Nature has recently published several breakthrough articles in this field of research. </div> <div><br /></div> <div>At Chalmers, several research groups are working at the forefront of graphene. The Graphene Centre is now investing in new infrastructure in order to be able to broaden the research area to include other 2D materials and heterostructures as well.</div> <div><br /></div> <div>“We want to establish a strong and dynamic hub for 2D materials here at Chalmers, so that we can build bridges to industry and ensure that our knowledge will benefit society,” says Ermin Malic.</div></div> <div>​<br /></div> <div></div> <div><span style="background-color:initial">Text and image: Mia Halleröd Palmgren, </span><a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a><br /></div> <div>Translation to English: Joshua Worth,<a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se</a></div> <div><br /></div> <div>Read the scientific paper <span style="background-color:initial"><a href="https://www.nature.com/articles/s41563-019-0337-0">Ultrafast transition between exciton phases in van der Waals heterostructures</a> </span><span style="background-color:initial">in Nature Materials.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><div><a href="https://idw-online.de/en/news713803"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release from Regensburg University, Germany. </a></div> <div><br /></div> <div><a href="/sv/centrum/graphene/Sidor/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the Graphene Centre at Chalmers (GCC)</a></div> <span style="background-color:initial"></span></div> <div><br /></div> <h3 class="chalmersElement-H3">For more information: </h3> <div><a href="/sv/personal/Sidor/ermin-malic.aspx">Ermin Malic,​</a> Professor, Department of Physics and Director of the Graphene Centre, Chalmers University of Technology, Sweden, +46 31 772 32 63, +46 70 840 49 53, <a href="mailto:ermin.malic@chalmers.se">ermin.malic@chalmers.se​</a></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/SamuelBremErminMalic_20190415_bannerwebb.jpg" alt="" style="margin:5px" /><br />Professor Ermin Malic (to the right) and his doctoral students Samuel Brem (left) and <span style="background-color:initial">Simon Ovesen (not pictured) r</span><span style="background-color:initial">ecently collaborated with researchers at Regensburg University.

The idea came from Robert Rehammar (to the left), CTO at Bluetest, and he also welcomed the students to the introduction in the lecture hall Kollektorn.</span><br /></div> <div>&quot;In Gothenburg we are very good at microwaves. One might say that we are one of the four best places in the world in the area&quot;, he said.</div> <div><br /></div> <h5 class="chalmersElement-H5">Strong growth</h5> <div>Microwave Road connects a number of companies and institutions in the region with microwave technology as a common denominator. It is an area of ​​strong growth and with a great need for competent workforce.</div> <div>&quot;By showing you some of all the cool things that can be done with microwaves, we want to try to get you interested&quot;, Robert Rehammar said.</div> <div><br /></div> <div>With him in Kollektorn were Hans Hjelmgren, associate professor of microwave technology and program manager for the MSc program in electrical engineering at Chalmers, Jonas Flygare, doctoral student at Onsala Space Observatory, Magnus Rissvik, Alessandro Cartabellotta and Yuki Kubota, all three from Ericsson, and Edit Helgee, Qamcom.</div> <div><br /></div> <div>Microwave technology is available in considerably more contexts than the classic radar motifs with flashing dots seen in action films, and rotating objects on top of the passenger ferries' navigation bridges. In fact, microwaves are used everywhere today, but we may not think about it. The 125 eighth graders learned more about all this in short presentations and exercises.</div> <div><br /></div> <h5 class="chalmersElement-H5"><img src="/SiteCollectionImages/Institutioner/MC2/News/microwave_IMG_6817_350x305.gif" class="chalmersPosition-FloatRight" alt="Picture from microwave event." style="margin:5px" />Makes traffic safer</h5> <div>Edit Heelge (to the right) from Qamcom works with radar systems for cars:</div> <div>&quot;We are investigating how radar measures distance, speed and direction and how to use it to make traffic safer&quot;, she told.</div> <div><br /></div> <div>In his job as a doctoral student at Onsala Space Observatory, Jonas Flygare uses microwaves and radio telescopes.</div> <div>&quot;It's another way of looking at space. With microwave antennas as a telescope, we capture signals from stars very far from here&quot;, he explained.</div> <div><br /></div> <div>Magnus Rissvik talked about how Ericsson develops and sharpens the connected society in different ways. Among other things, they have a project in collaboration with SMHI that makes it possible to visualize rainfall for the benefit of farmers and others.</div> <div>&quot;Microwaves are affected by moisture and rain. With the help of radio links we can measure how much it has been raining locally, and see exactly where it rained and how much. Farmers can find out if it has rained on their land or if they may need to water it&quot;, Magnus Rissvik told us.</div> <div><br /></div> <h5 class="chalmersElement-H5">Huge labour market</h5> <div>Hans Hjelmgren stroke a blow to start studying electrical engineering at Chalmers:</div> <div>&quot;There is a lot going on in electrical engineering, now and in the next few years. The labour market is huge. It is about the connected society where we talk to each other, use mobile phones and have started talking to cars, which in turn speak to the traffic lights. Different things are connected to each other. All this communication is done with microwaves&quot;, said Hans Hjelmgren.</div> <div>He continued:</div> <div>&quot;It can be difficult to study at Chalmers, but it is also very fun. There is a lot of fun that one can engage in beside the studies; air-balloon, ice hockey, cortège, spex and much more.&quot;</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/microwave_IMG_6767_350x305.gif" class="chalmersPosition-FloatRight" alt="Picture from microwave event." style="margin:5px" />Hans Hjelmgren (to the right) spoke about several exciting areas where microwave technology is applied, for example the mobile stroke helmet and the world-famous mind-controlled arm protease developed by Chalmers researcher Max Ortiz Catalan:</div> <div>&quot;It is so sensitive that you can pick up an egg with it&quot;, he said.</div> <div>In electrical engineering, you work a lot with electric vehicles and renewable electricity. Hans Hjelmgren took the opportunity to mention the self-driving bus that can be tested in Chalmers both campuses during test periods.</div> <div>&quot;So far, the bus goes quite slowly, but it runs around Chalmers completely on its own. We want the electricity for electric cars to come from renewable sources. At Chalmers we work with wind power and solar power&quot;, he said.</div> <div><br /></div> <h5 class="chalmersElement-H5">Four stations</h5> <div>Most of the event took place at four different stations that the students had to circulate between. Among other things, a drone appeared, the youngsters did a minor space observation and tested their mobile phones' performance in a mini-competition. The whole thing was very much appreciated and the young people asked many curious questions.</div> <div>&quot;They got to test their mobile phones, see how radars are used for self-driving cars, and how microwaves are used to understand the universe&quot;, says Hans Hjelmgren.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/microwave_IMG_6859_665x330.gif" alt="Picture from microwave event." style="margin:5px" /><br /><span style="background-color:initial">The event combined physics, technology and mathematics in an exciting way, and was included as part of The International Science Festival's ongoing school program.</span><br /></div> <div>Hans Hjelmgren was very happy with the day:</div> <div>&quot;Everything worked according to plan. We invited schoolchildren to explore the exciting world of microwaves. Hopefully some of them will appear at Chalmers in the future&quot;, he says.</div> <div><br /></div> <div>Text and photo: Michael Nystås</div>Thu, 11 Apr 2019 10:00:00 +0200https://www.chalmers.se/en/departments/physics/news/Pages/Worlds-fastest-hydrogen-sensor-could-pave-the-way-for-clean-hydrogen-energy.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Worlds-fastest-hydrogen-sensor-could-pave-the-way-for-clean-hydrogen-energy.aspxWorld&#39;s fastest hydrogen sensor could pave the way for clean energy<p><b>Hydrogen is a clean and renewable energy carrier that can power vehicles, with water as the only emission. Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers from Chalmers University of Technology, Sweden, present the first hydrogen sensors ever to meet the future performance targets for use in hydrogen powered vehicles.</b></p><div><p class="chalmersElement-P">​<span style="background-color:initial">The researchers’ ground-breaking results were recently <a href="https://www.nature.com/articles/s41563-019-0325-4">published in the prestigious scientific journal Nature Materials.​</a> The discovery is an optical nanosensor encapsulated in a plastic material. The sensor works based on an optical phenomenon – a plasmon – which occurs when metal nanoparticles are illuminated and capture visible light. The sensor simply changes colour when the amount of hydrogen in the environment changes.</span></p> <p class="chalmersElement-P">The plastic around the tiny sensor is not just for protection, but functions as a key component. It increases the sensor’s response time by accelerating the uptake of the hydrogen gas molecules into the metal particles where they can be detected. At the same time, the plastic acts as an effective barrier to the environment, preventing any other molecules from entering and deactivating the sensor. The sensor can therefore work both highly efficiently and undisturbed, enabling it to meet the rigorous demands of the automotive industry – to be capable of detecting 0.1 percent hydrogen in the air in less than a second.</p> <img src="/SiteCollectionImages/Institutioner/F/350x305/Ferry_portratt_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:216px;width:250px" /><p class="chalmersElement-P">“We have not only developed the world's fastest hydrogen sensor, but also a sensor that is stable over time and does not deactivate. Unlike today's hydrogen sensors, our solution does not need to be recalibrated as often, as it is protected by the plastic,” says Ferry Nugroho, a researcher at the Department of Physics at Chalmers.</p> <p class="chalmersElement-P">It was during his time as a PhD student that Ferry Nugroho and his supervisor Christoph Langhammer realised that they were on to something big. After reading a scientific article stating that no one had yet succeeded in achieving the strict response time requirements imposed on hydrogen sensors for future hydrogen cars, they tested their own sensor. They realised that they were only one second from the target – without even trying to optimise it. The plastic, originally intended primarily as a barrier, did the job better than they could have imagined, by also making the sensor faster. The discovery led to an intense period of experimental and theoretical work.</p> <p class="chalmersElement-P">“In that situation, there was no stopping us. We wanted to find the ultimate combination of nanoparticles and plastic, understand how they worked together and what made it so fast. Our hard work yielded results. Within just a few months, we achieved the required response time as well as the basic theoretical understanding of what facilitates it,” says Ferry Nugroho.</p> <p class="chalmersElement-P">Detecting hydrogen is challenging in many ways. The gas is invisible and odourless, but volatile and extremely flammable. It requires only four percent hydrogen in the air to produce oxyhydrogen gas, sometimes known as knallgas, which ignites at the smallest spark. In order for hydrogen cars and the associated infrastructure of the future to be sufficiently safe, it must therefore be possible to detect extremely small amounts of hydrogen in the air. The sensors need to be quick enough that leaks can be rapidly detected before a fire occurs.</p> <img src="/SiteCollectionImages/Institutioner/F/350x305/ChristophLanghammerfarg350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:216px;width:250px" /><p class="chalmersElement-P">​“It feels great to be presenting a sensor that can hopefully be a part of a major breakthrough for hydrogen-powered vehicles. The interest we see in the fuel cell industry is inspiring,” says Christoph Langhammer, Professor at Chalmers Department of Physics.</p> <p class="chalmersElement-P">Although the aim is primarily to use hydrogen as an energy carrier, the sensor also presents other possibilities. Highly efficient hydrogen sensors are needed in the electricity network industry, the chemical and nuclear power industry, and can also help improve medical diagnostics.</p> <p class="chalmersElement-P">“The amount of hydrogen gas in our breath can provide answers to, for example, inflammations and food intolerances. We hope that our results can be used on a broad front. This is so much more than a scientific publication,” says Christoph Langhammer.</p> <p class="chalmersElement-P">In the long run, the hope is that the sensor can be manufactured in series in an efficient manner, for example using 3D printer technology.<br /><br /></p> <div><strong>Text: </strong><span style="background-color:initial">Mia Halleröd Palmgren,</span><span style="background-color:initial"> </span><a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a> and <span style="background-color:initial">Joshua Worth,</span><a href="mailto:joshua.worth@chalmers.se"> joshua.worth@chalmers.se</a><span style="background-color:initial">​ </span></div> <div><strong>Image</strong> of C<span style="background-color:initial">hristoph</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"> Langhammer: Henrik Sandsjö</span><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><strong>Illustration</strong> of the sensor technique: </span><span style="background-color:initial">Ella Marushchenko<br /></span><span style="background-color:initial">Images of Ferry Nugroho, the sensor and the group picture: Mia Halleröd Palmgren​</span></div></div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/Vatgassensor_750x340.jpg" alt="" style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;font-size:24px;background-color:initial;margin:5px" /> ​</div> <h4 class="chalmersElement-H4"><span>Facts: The world's fastest hydrogen sensor​</span><span>​</span></h4> <div><span style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;background-color:initial"><br /></span></div> <div><ul><li><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/vätgassensor_amerikansk_illu350x460.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:250px;height:324px" /><span style="background-color:initial">The Chalmers-developed sensor is based on an optical phenomenon – a plasmon – which occurs when metal nanoparticles are illuminated and capture light of a certain wavelength.</span></li> <li><span style="background-color:initial"></span>The optical nanosensor contains millions of metal nanoparticles of a palladium-gold alloy, a material which is known for its sponge-like ability to absorb large amounts of hydrogen.

We have several different categories of employees at the department and the gender distribution is very different in different groups. A basic rule when it comes to gender equality, I think, is that 'nobody should be prevented, forced, or expected to do anything because of their gender affiliation'&quot;, Per Rudquist says.</div> <div><br /></div> <div>He also wants to work with the workplace culture at MC2, about raising awareness of how we unconsciously and consciously express ourselves and treat each other. The gender gap in research and technology is another area that engages the new equality representative:</div> <div>&quot;I've been thinking about the causes for a long time and reacting in particular to the fact that we often use statistics to assign individuals certain properties. We are already starting when the children are small and it continues up into adulthood.

Cell membranes play a key role in many biological processes and diseases. The membrane is essential for the cell’s ability to communicate with its surroundings.

These so-called sub-cycle pulses can be used to probe and control matter in unique ways. Conventional methods can only produce sub-cycle pulses of limited field strength: above a certain threshold the amplifying medium would be ionized by the intense fields. The researchers propose to use an electron beam in a plasma, which is not subject to a damage threshold, as an amplifying medium for a seed electromagnetic pulse. To ensure that energy is transferred from the electron beam to the pulse in such a way that a sub-cycle pulse is produced, the beam needs to be introduced at an appropriate phase of the oscillation of the electromagnetic field. This can be achieved by using a mirror to reflect the seed pulse while the electron beam is being injected. This scenario leads to significant amplification of the seed pulse and the formation of an intense, isolated, sub-cycle pulse. Readily available terahertz seed pulses and electron bunches from laser-plasma accelerators could generate mid-infrared sub-cycle pulses with millijoule-level energies, which are highly desirable as probes of matter but not possible to produce with conventional sources.</div> <div><br /> </div> <h4 class="chalmersElement-H4">For more information: </h4> <div><a href="http://www.chalmers.se/en/Staff/Pages/Illia-Thiele.aspx">Illia Thiele</a>, Postdoctoral researcher, Department of Physics, Chalmers University of Technology, +46 76 607 82 79,<a href="mailto:illia.thiele@chalmers.se"> illia.thiele@chalmers.se</a><br /></div> <div> </div> <div><span style="background-color:initial"><a href="/en/staff/Pages/Tünde-Fülöp.aspx">Tünde Fülöp,​</a> Professor, Department of Physics, Chalmers University of Technology, +46 72 986 74 40, </span><a href="mailto:tunde.fulop@chalmers.se">tunde.fulop@chalmers.se</a></div> <div><br /><a href="https://www.physics.gu.se/english/about-the-department/staff/?languageId=100001&amp;disableRedirect=true&amp;returnUrl=http://www.physics.gu.se/om-institutionen/personal/?languageId%3D100000%26userId%3Dxsimev&amp;userId=xsimev">Evangelos Siminos</a>, Assistant Professor, Department of Physics, University of Gothenburg</div></span><div><span style="background-color:initial">+46 31 786 9161, <a href="mailto:evangelos.siminos@physics.gu.se">evangelos.siminos@physics.gu.se</a></span></div>Tue, 19 Mar 2019 07:00:00 +0100https://www.chalmers.se/en/departments/mc2/news/Pages/Introductory-lecture-by-new-assistant-professor.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/Introductory-lecture-by-new-assistant-professor.aspxIntroductory lecture by new assistant professor<p><b>​Attila Geresdi will enter a new assignment as assistant professor at MC2 on 1 September.

However, it is not always reliable. There is a risk that signals are picked up from the mother's heart rather than the foetus’s, which can have serious consequences. Our way of measuring is potentially more precise, thanks to the advanced electrodes that are now available. We can measure and, using our specially developed analysis, distinguish the foetus’s heartbeat, which can be hundreds of times weaker than the mother’s at the end of pregnancy,” says Albin Annér, one of the prizewinners.        </span></div> <div> </div> <div>The electrodes measure electrical fields in the skin. Unlike with a CTG device, however, they need not be fixed directly onto the skin. The mother does not have to be closely connected to a device, giving her greater freedom of movement. The method is also completely harmless because no current flows between the mother and the electrodes. </div> <div> </div> <div>“Their method is very promising.

In different ways, all three programmes focus on the needs and solutions of our digitalised future.</b></p>​<span style="background-color:initial">The demand for skills in data science and artificial intelligence is heavily increasing. Courses in these subjects already exist in programmes at Chalmers, but with the extensive interest from both students and industry, the Master’s programme <em>Data Science</em> has now been created. It specifically focuses on increased digitalisation. </span><div><br /><span style="background-color:initial"></span><div>The interest in Chalmers programmes in Computer Science has also increased during the last few years. To meet the high demand, a new programme called <em>High-Performance Computer Systems</em> will start. The programme aims to give students cutting-edge expertise in computer systems engineering, with a focus on the future use of computing.</div> <div><br /></div> <div>“The interest in our two new Master’s programmes is great, both here at Chalmers, and externally from industry. The great social upheaval that is made possible by digitalisation is leading to an increased need for qualified competence in Computer Science. I believe that the development of this type of education has only begun”, says Jörgen Blennow, Dean of Education for the educational area Electric, Computer, IT and Industrial Engineering at Chalmers. </div> <div><br /></div> <div>At the educational area for Physics, the two Master’s programmes <em>Applied Physics</em> and <em>Physics and Astronomy</em> have been the base for a whole new programme, called <em>Physics</em>. Anders Hellman, Director of the new Master's programme, says that with a new, creatively developed programme and new courses, they want to give the students more than just the skills needed in the industry today, thereby preparing them for a digitalised future.</div> <div><br /></div> <div>“The students will receive knowledge in the areas of physics that in different ways are key to the advanced technologies of today and tomorrow. We want the students to get generic and long-term knowledge in physics that not only helps them with solutions for the needs of today, but that also prepares them for the challenges of the future industry, challenges that we cannot even foresee today.”</div> <div><br /></div> <div>The programme offers five specialisations – <em>Astronomy, Biological Physics, Computational Physics, High-energy Physics</em> and <em>Materials Science</em>. The programmes <em>Applied Physics</em> and <em>Physics and Astronomy</em> close when the new programme starts.</div> <div><br /></div> <div>For international students, two of the new Master’s programmes that start in autumn 2019 are still open for late application – <em>High Performance Computer Systems</em> and <em>Physics</em>.
