Anton Frisk-Kockum and Raphaël Van Laer both receives a grant of 15 million SEK each over a five-year period and will during the program participate in a solid leadership training.</b></p><div>​“I’m both humbled by the trust in me and my research ideas that SSF shows by awarding this grant, and excited to start the project”, says Anton Frisk Kockum, who receives the grant for the project “Quantum simulation and communication with giant atoms”.</div> <div><br /></div> <div>The project aims to harness a new regime of light-matter interaction, so-called giant atoms, for useful applications. In these systems, interference effects make it possible to turn on and off the coupling between a system emulating the properties of an atom and a surrounding environment.</div> <h2 class="chalmersElement-H2">Two purposes</h2> <div>&quot;I will use this setup for two purposes: first to efficiently simulate quantum systems of interest (e.g., molecules) that interact with their surroundings, and second to enable communication between quantum systems, e.g., two quantum-computing processors&quot;, says Anton Frisk Kockum. </div> <div><br /></div> <div>&quot;This funding will let me create a research group devoted to giant atoms and their applications. I currently have one PhD student working on these topics. I will now recruit one postdoc and one more PhD student. The funding also comes with an excellent leadership training program, which I look forward to participating in and learning from.&quot;</div> <div><h2 class="chalmersElement-H2">Overlooked potential in acoustic and optical devices<br /></h2></div> <div>Raphaël Van Laer receives the grant for his project “Attojoule-per-bit acousto-optics”.<br /><br />&quot;Society relies heavily on transistor-based information technologies such as computers and the internet. These systems became increasingly powerful in what is known as Moore’s law. Today, this trend is faltering as transistors are reaching performance limits. The project’s goal is to lay the foundations for new types of information technology with chip-scale light and sound&quot;, he says.<br /><br />He aims to greatly reduce the energy footprint of emerging coherent information processors based on photonics and quantum technology.<br /></div> <div><h2 class="chalmersElement-H2">High hopes and aspirations<br /></h2> <div>&quot;The broad potential of acousto-optic interactions has mostly been overlooked. In this project, we will develop near-term use-cases of acoustic and optical devices and especially in quantum technology. This will synergize well with the more fundamental quantum engineering we do&quot;, he says. He adds that it feels very exciting and humbling to receive the grant, and that it is a great opportunity that comes with great responsibility.</div> <div> </div> <div>&quot;We are a small team in quantum photonics with a new laboratory supported mainly by the EU and WACQT. The new SSF grant will make a big impact on our ability to pursue risky ideas and build critical mass. Our hopes and aspirations are high. The grant gives us a mandate to be brave and to keep going especially when things become difficult. We need to adapt and learn quickly from trial-and-error. I am also eager to join SSF's leadership program. Finally, I believe that the project will be well-suited for near-term interaction with related work at MC2. I look forward to exploring this with colleagues in photonics and quantum engineering&quot;, he says.</div></div> <div><br /></div> <h2 class="chalmersElement-H2">Contact</h2> <div><a href="/en/staff/Pages/Anton-Frisk-Kockum.aspx">Anton Frisk Kockum</a>, Researcher, <a href="mailto:anton.frisk.kockum@chalmers.se">anton.frisk.kockum@chalmers.se</a>, +46317723190<br /></div> <div><span><a href="/en/staff/Pages/raphael-van-laer.aspx">Raphaël Van Laer</a>, <span></span></span>Assistant Professor, <a href="mailto:raphael.van.laer@chalmers.se">raphael.van.laer@chalmers.se</a>, +46317724030<br /></div> <div><br /></div> <div>Text: Robert Karlsson</div> <div><br /></div> <h2 class="chalmersElement-H2">Read more</h2> <div><a href="/en/news/Pages/They-are-the-future-research-leaders.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />They are the Future Research Leaders</a>, www.chalmers.se</div> <div><a href="https://strategiska.se/en/they-are-the-research-leaders-of-the-future-framtidens-forskningsledare/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />SSF press release</a>, www.ssf.se<br /></div>Mon, 27 Jun 2022 11:00:00 +0200https://www.chalmers.se/en/news/Pages/They-are-the-future-research-leaders.aspxhttps://www.chalmers.se/en/news/Pages/They-are-the-future-research-leaders.aspxThey are the Future Research Leaders<p><b>​No less than six Chalmers researchers were accepted when the Swedish Foundation for Strategic Research, SSF, appointed Future Research Leaders. </b></p><div>​The goal of the program is to give newly established researchers with the highest scientific and pedagogical competence the opportunity to develop as research leaders.

Nearly 300 users of Nordic universities' nanofabrication laboratories had the opportunity to meet, take part in lectures and tutorials, and discuss research ideas and results with each other.&quot;The most important signal we send is that there will always be better results if we do things together,&quot; says Thomas Swahn, head of Myfab, the Swedish infrastructure that includes Myfab Chalmers, the nanotechnology laboratory at MC2.</b></p><div>​The user meeting NNUM took off in Trondheim in 2017. In 2019, the meeting was held in Copenhagen, and in 2021 it was Gothenburg and Chalmers' turn to run the show. When the pandemic meant that the user meeting could not be arranged on site, the organizers chose to postpone the physical meeting to 2022.</div> <div> </div> <div><br /> </div> <div>Nearly 300 people from all over the Nordic region participated during the two days. In his role as head of Myfab, Thomas Swahn was the one responsible for arranging NNUM in 2022, and he is more than pleased with the outcome.</div> <div><br /> </div> <div>&quot;The most important thing is to present the labs, and what we are capable of doing&quot;, says Thomas Swahn. &quot;The meeting works as a good opportunity for interaction, where we learn from each other and can find synergies. 'Come here and test your ideas!'&quot;</div> <h2 class="chalmersElement-H2">Four different tracks</h2> <div>During the two days, three major presentations were held on the theme of nanoresearch, including one on quantum computers held by Chalmers' Jonas Bylander. Otherwise NNUM was divided into four different thematic tracks with five presentations – tutorials – in each where basic as well as advanced techniques were presented. The meeting participants chose for themselves which track they wanted to attend. The four tracks followed the specializations in nanofabrication work that previously have been established within the Nordic network: characterization, thin film technology, etching and lithography.</div> <div> </div> <div><br /></div> <div>&quot;If you're lucky, there might be someone or some people who know the same thing as you, but often there's only one expert in a field. So we did these pretty broad focuses in the expert network&quot;, says Thomas Swahn. “All in all, it can be said that the different tracks constituted a smorgasbord of the advanced manufacturing capabilities on the micro and nano scale that the Nordic Nanolab Network offers to researchers and entrepreneurs.”</div> <div> </div> <div><br /> </div> <div>In addition to presentations and tutorials, a poster competition was organized where researchers had the opportunity to contribute with a research poster that presents results made possible by the researchers having open access to the opportunities offered by the laboratories. Mahdi Shanei, PhD student at the Department of Physics at Chalmers, was one of the three who were awarded a prize for their poster.</div> <div><h2 class="chalmersElement-H2"> Optics and metasurfaces</h2></div> <div><img src="/sv/institutioner/mc2/nyheter/PublishingImages/220512%20Mehdi%20Shanei.jpeg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:300px;height:400px" />&quot;I think to have a good poster, we need to chose a single aspect of our research that we can explain fully in a small amount of text and graphics and focus on that alone&quot;, he says. &quot;Obviously, passersby will look at the title first, so it is good to make it as interesting and informative as possible.&quot;</div> <div><br /></div> <div>Mahdi Shanei's research is about optics and metasurfaces. Metasurfaces consist of carefully designed and interacting nanoparticles that can control light in unusual and innovative ways. Future time application areas can be cameras, microscopes, electronic displays and other technology that requires advanced optical components.</div> <div><br /></div> <div>&quot;In the presented poster, we investigate the design and fabrication of a compact and contact-less optical tweezer with the use of a metasurface. The introduced metasurface is able to trap and transport microparticles along a straight line in the far-field region. Our work comprises a first demonstration of transporting multiple particles over a wide area using a metasurface-based system&quot;, says Mahdi Shanei.</div> <div><br /></div> <div>Mahdi Shanei emphasizes the great benefit of meeting other nanofabrication lab users and being able to discuss common research interests with them, and that the large number of participants and the variety of research projects provided opportunities to find projects similar to one's own and have fruitful discussions.</div> <div><br /></div> <div>&quot;Although there was an overlap between the thematic tutorial sessions, I found most of them very useful for Myfab users&quot;, he says. </div> <div> </div> <h2 class="chalmersElement-H2">About NNUM and Myfab</h2> <div> NNUM bring nanofabrication laboratories at higher education institutions in Sweden, Norway, Denmark, Finland and Iceland together.

Here you can read about his research, and his thoughts on his time as PhD student.</b></p><strong>We recently made a </strong><a href="/en/departments/mc2/news/Pages/A-potential-breakthrough-for-production-of-superior-battery-technology.aspx" target="_blank"><strong>press release regarding the micro supercapacitors</strong></a><strong> that you wrote a scientific article about. Now you’ve had <a href="https://doi.org/10.1021/acsaem.1c03745" target="_blank">another publication about this</a>. What is it that you’ve done this time, and how does it connect with your earlier publication and work?</strong><br /><div><br /></div> <img src="/sv/institutioner/mc2/nyheter/PublishingImages/Agin%20Vyas.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:300px;height:312px" />&quot;So, previously we had demonstrated fabrication of micro energy storage units called Microsupercapacitors through “enhanced spin coating” methodology that can be implemented with integrated circuit (IC) fabrication using only one material such as graphene oxide, or vertically aligned carbon nanosheets, and carbon nanotubes. While, the spin coating method can demonstrate high coverage of material inks, increased uniformity and adhesion; these devices cannot exhibit high enough energy densities due to the layered thickness. In this article, we have shown that the microsupercapacitor performance can be improved by utilization up to four different materials, all layered through the same fabrication process i.e. spin coating. <br /><br /> <div><br /></div> <div>These materials are composites of graphene oxide synthesized by Dr. Ulises Mendez, especially tailored for improved spin coating and incorporation of novel 2D materials that are presently being researched at various energy storage material centers. The device performance of the stack of electrodes results in a up to three times higher performance compared to our previous publication without completely overhauling a preset fabrication process. This publication leads us closed towards standardized IC compatible integration of Microsupercapacitors while incorporating various synergistic effects from latest energy storage materials developed at state of the art labs.&quot;</div> <br /><div><strong>Your dissertation is April 29. Tell me about the topic of your work as a doctoral student, and why you wanted to focus on that in particular?</strong></div> <div><br /></div> <div>&quot;The topic of my dissertation is “On-chip electrochemical capacitors and piezoelectric energy harvesters for self-powering sensor nodes”. In this work, we have demonstrated successful fabrication of Microsupercapacitors as on-chip solution for energy storage  and silicon  cantilevers based on two degree of freedom structures to validate a large bandwidth of frequencies that have the potential to harvest vibrational energy, also on-chip. In this work, I have mainly focused on understanding the requirements of an on-chip power supply that can be in some sense “ever-lasting” through ambient energy harvesting and high cyclic stability of Microsupercapacitors. A combination of these units with a power conditioning circuit can potentially replace, as a long term aim, and complement, in the short-term, batteries. We wanted to focus of replacing batteries, because, in-spite of being a better solution to fuels, the batteries cannot achieve high power densities that are required for short bursts of applications, eg, vehicles  with hybrid powering technologies still cannot be used for transportation of heavy loads while driving up a slope. A supercapacitor with an energy harvesting source can act as complementary units with the energy storage system module that can provide such short power bursts.&quot; </div> <br /><div><strong>What are the most important findings, would you say?</strong></div> <strong> </strong><div><br /></div> <div>&quot;The most important findings for my PhD can be described as follows:</div> <br /><div>Vibrational energy harvesting is an attractive solution for micro power harvesting from areas that are inaccessible to sunlight, heat, or human interaction.  Their utility however is limited to the bandwidth of useable frequencies. In order to improve the bandwidth, application of two degree of freedom (2DOF) cutout cantilevers can be a potential solution. Advantages of improved bandwidth and relative feasibility of fabrication through IC processing make them a stand out solution among a myriad of other promising solutions. Another important finding for vibrational energy harvester concerns the gap between the design and fabrication constraints. It is extremely important to address trade-offs of designing and manufacturing. </div> <div><br /></div> <div>Energy storage through batteries and supercapacitors is often a bottleneck for miniaturization of sensor nodes for wireless sensor networks. Thus, miniaturization to Microsupercapacitors is the next stage of evolution for on-chip energy solutions. While several promising materials have emerged through continuous research in nanomaterials, graphene as an energy storage material is close to integration with various IC technologies. Using graphene based inks deposited through conventional IC compatible methodology such as spin coating can be challenging due to its flake size and substrate roughness. Increasing the roughness of a substrate can improve the adhesion, coverage, and uniformity of the spin coated graphene ink, leading to an improved yield in the IC compatible device fabrication. The energy density of the Microsupercapacitors can be improved by stacking several materials spin coated on the same substrate using enhanced surface roughness technique without tweaking a standardized fabrication process.&quot;</div> <br /><div><strong>What challenges have you been facing along the way?</strong></div> <strong> </strong><div><br /></div> &quot;To name a few would be a dis-service to the ones I have forgotten. PhD students are expected to know how to do “everything” and the steep learning curve that is demanded for developing new advancements is often challenging. We can often forget the time that is required to learn, re-learn and sometime un-learn a skill. Another challenge that perhaps we all encountered was a once in a lifetime pandemic. I don’t think we have still recovered from the loss that we all suffered in that time.  I think the challenges of a PhD student cannot be limited to just research. It is becoming more and more important to address issues of mental stress with PhD studies and demands of academia.  We have come from various communities across the world with different dreams, aims, and aspirations to a country which every person in the world can be proud of. However, the immigration policy of Migrationsverket is often an a severe source of stress for us. Not only does it fill us with insecurity about the future, but it also acts as a barrier for many of us to be completely immersed in the beautiful surroundings and act in healthy and positive ways. I think it would be important to address these issues in collaboration with PhD students, faculty, institute, and policy makers in the future for a healthy and sustainable functioning to the technology cycle.&quot;<br /><br /><strong>What’s your plans for the future?</strong><br /><div><br /></div> <div>&quot;As of now, I want to rest on the 30th after knowing what happens on 29th. Sunny weather will be welcome. Maybe a trip to Thailand. Otherwise, I plan to continue development of microsupercapacitors as viable energy storage units. I think such a device can be a solution to energy storage problem, we are facing right now. Otherwise, my focus would be on being in better health, spending more time with my loved ones, and working towards making our society better, more inclusive, and peaceful.&quot;</div> <div><br /></div> <div><a href="/en/departments/mc2/calendar/Pages/Agin-Vyas.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />More information about Agin Vyas' dissertation<br /></a></div> <div><br /><a href="/en/departments/mc2/calendar/Pages/Agin-Vyas.aspx" target="_blank"></a></div> <div>Text: Robert Karlsson</div> <div>Photo: Agin Vyas<br /></div> <span lang="EN-US" style="font-size:11pt;line-height:107%;font-family:&quot;calibri&quot;, sans-serif"></span>Tue, 26 Apr 2022 11:00:00 +0200https://www.chalmers.se/en/departments/mc2/news/Pages/new-Bridge-centre-inaugurated.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/new-Bridge-centre-inaugurated.aspxKickoff meeting for the new GigaHertz-ChaseOn Bridge center<p><b>​Starting this spring, two of Chalmers’ successful competence centres, GHz Centre and ChaseOn, join forces and become the new &quot;GigaHertz-ChaseOn Bridge center&quot;.

Working as a researcher and being a parent of young children is an even greater challenge. At the Department of Microtechnology and Nanoscience, a family room has been built to make life easier and to make it easier for staff to put the pieces of their everyday lives together.</b></p>​The green sofa in the corner of the room does not stand out in any way. <br />The Indian tent that stands next to the sofa possibly stands out a little more. The walls in the room room are not adorned by research posters showing the state of different nanoparticles, but by drawings of rainbows and unicorns, signed by Sara, Hannah and Tiahana.<br /><div><br /></div> <div>At the end of 2021, the Department of Microtechnology and Nanoscience, MC2's, family room was officially inaugurated. What used to be an anonymous room intended for a few minutes of coffee with colleagues, is now instead decorated with bookshelves filled with games and toys. A toy kitchen made out of wood and a rugged colorful plastic rug on the floor tells us that this is no ordinary office or staff space. In one of the corners of the room there is a desk with a computer screen where a visitor can plug in and work, but there is no doubt that the room has been decorated primarily for a younger group to thrive there.</div> <h2 class="chalmersElement-H2">A room with a lot of possibilites</h2> <div>As an employee of MC2 – or the Department of Physics, who is involved in sharing the space – the staff can book the room, bring their child there, and work there while the child can play with games and toys. The room is also available for use for visiting employees or speakers at seminars who travel to Gothenburg with their children, and it can also be used if an employee needs to have external babysitting during working hours.<br /></div> <div><br /></div> <div>So where did the idea for a family room come from?</div> <div><br /></div> <div>“From a need”, says Janine Splettstößer and smiles.</div> <div><br /></div> <div>She is a professor of theoretical physics at MC2, parent of three children, and now also &quot;mother&quot; of the department’s family room.</div> <div><br /></div> <div>&quot;My husband and me are both researchers and being parents of young children can sometimes make it difficult to organize everyday life”, she says. “Previously, I had a blanket on the floor of my office where my kids could play if I brought them to work. The collegaues and the working place were always understanding, but it is still not that easy and it also becomes a bit boring for the children.”</div> <div><h2 class="chalmersElement-H2">Genie gave the green light</h2></div> <div><img src="/sv/institutioner/mc2/nyheter/PublishingImages/220321%20Familjerummet%202.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:350px;height:170px" />When Chalmers’ foundation initiative Genie, which works to make Chalmers a more equal working place, made an internal call in autumn of 2019 for Chalmers researchers to apply for funding for projects that would strengthen gender equality at Chalmers, Janine Splettstößer seized the opportunity. At a visit at the Technical University of Münich in Münich, she had noted that there was a room intended for staff where they could leave their children. Would it be possible to do something similar at Chalmers?</div> <div><br /></div> <div>&quot;I asked the head of my department, Mikael, if he thought it was a good idea to do if we could find a suitable room, and he said yes. So I went ahead and applied and got money from Genie, and then it took some time for us to find a room. Mikael has been a great support in this work – without him there would have been nothing with this”, she says.</div> <div><br /></div> <div>For Mikael Fogelström, head of department at MC2, the family room is a great example of how employees identify and communicate a need in the organization.</div> <div><br /></div> <div>&quot;Janine has been very clear that it must be possible to be able to have a career as a researcher and to be a parent at the same time. Children may need to be at their parents’ workplace for a variety of reasons, and an initiative like this can make life a little easier for all employees who have children of different ages,&quot; he says.</div> <div><h2 class="chalmersElement-H2">Community building factor</h2> <div> </div></div> <div>He emphasizes how a family room also serves as a community building factor for the department, the fact that it can lead to staff being able to meet other staff who are in the same situation, being a help to build networks both inside and outside the workplace.</div> <div><br /></div> <div>&quot;To be a researcher is to work in a very international environment, and it is not always easy to be a new member of a society. Such an initiative as the family room can bring people in the same situation together. If I feel that others are struggling the same way as I do, it can make the burden feel easier to carry”, he says.</div> Maria Saline is the coordinator of Genie. She says it was an quick and easy decision deciding on supporting the building of a family room.<br /> <div><h2 class="chalmersElement-H2">An application that stood out</h2></div> <div>&quot;Janine's application stood out and therefore got in the spotlight,&quot; she says. “We liked that it was a different approach than most of the other applications, and the purpose from Genie's point of view was to support as many different kinds of equality approving ideas as possible.”</div> <div><br /></div> <div>But even if the support for a family room was an obvious thing for Genie, Maria Saline does not see the issue as completely unproblematic. Having access to a family room can of course make everyday life easier, but at the same time, for instance, it should not send the signal that one is always available for work.</div> <div><br /></div> <div> &quot;Sweden differs in many ways from much of the rest of the world,&quot; she says. ”We are unique in many ways in how we have built our society, for instance with childcare. For many universities in the world, this kind of model or similar ones are a way of solving such things. We don't have to do that in Sweden, and Genie shouldn't do what our society already does.”</div> <div><br /></div> <div>At the same time, she emphasizes the positive effects that a family room generates, and that the issue is not black or white. In the very international environment that academia is, there is often an attitude that working as a researcher is a big part of your whole life, that it is more of a lifestyle.</div> <div><br /></div> <div>&quot;Research groups interact very intensively with each other, and getting into Swedish society can be difficult,&quot; she says. “A family room can become a room to meet others in, and thus actually help to find and create the balance between working life and social life, to also affirm the life outside of work.”</div> <h2 class="chalmersElement-H2">Contact</h2> Janine Splettstößer, professor in theoretical physics<br /><div><a href="mailto:janines@chalmers.se">janines@chalmers.se</a>, +46317723111</div> <div><br /></div> <div>Text and photos: Robert Karlsson<br /></div> <div> </div>Mon, 11 Apr 2022 15:00:00 +0200https://www.chalmers.se/en/departments/mc2/news/Pages/New-adjuncts-strengthen-MC2's-cooperation-with-industry.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/New-adjuncts-strengthen-MC2's-cooperation-with-industry.aspxNew adjuncts strengthen MC2's cooperation with industry<p><b>​Dr. Rui Hou and Dr.  Mingquan Bao, both employees at Ericsson, have been co-opted as adjunct associate professor and adjunct professor respectively at the Department of microtechnology and nanoscience (MC2), Chalmers University of technology.

The platform provides teachers and students with a common educational environment and access to the same information, so that students have equal learning opportunities regardless of geographical location and individual level of knowledge. They have now been awarded the Bert-Inge Hogsved Award for Best Entrepreneurship by the Forum for Engineering Physicists at Chalmers.  </b></p><div><span style="background-color:initial"><strong>Simon Pettersson Fors</strong> and <strong>Eric Lindgren</strong> are the recipients of this year’s <a href="https://tekniskafysiker.wordpress.com/bert-inge-hogsveds-pris/">Bert-Inge Hogsved Award for Best Entrepreneurship</a>. The award was established in 2011 by <strong>Bert-Inge Hogsved</strong>, himself an engineering physicist. The award is presented annually to students studying the programmes Engineering Physics, Engineering Mathematics or Chemical Physics with Engineering Physics. The intention is to highlight entrepreneurial initiative among students at Chalmers. </span></div> <div><br /></div> <div><span style="background-color:initial"></span>A study conducted by the Swedish Board of Student Finance (CSN) in 2020 revealed that diminished mental wellbeing is significantly more common among students than skilled workers. Studies were perceived as overly demanding and stressful. </div> <div><br /></div> <div>“As a student, one is often frustrated, unable to make progress, something that creates stress. On our learning platform, it is easy to get help. Anyone can ask a question and it can be answered by both other students and teachers. All students remain anonymous in order to remove the stigma attached to ignorance,” Simon Pettersson Fors, doctoral student at the Department of Microtechnology and Nanoscience.</div> <div><br /></div> <div>The learning platform, Yata, is an open forum that facilitates joint discussion to solve various problems. As all questions and answers are available to everyone, the platform can help many students simultaneously. All information is saved for posterity, making the learning platform a knowledge bank for future students and a tool for streamlining teaching.</div> <div><br /></div> <div>For teachers, the primary benefit is saved time. A teacher can speak to the entire group at once, rather than emailing individual students. It also provides them with an opportunity to check that students are on the right track in their reasoning and plan the next stage of teaching based on ongoing discussions in the forum. They can also use earlier pedagogical posts by former teachers and students. </div> <div><br /></div> <div>“There are many learning platforms on the market but few aimed at learning physics, engineering and mathematics at higher education level.

Manufacturers of everything from smartphones to electric cars are therefore investing heavily into research and development of these electronic components. Now, researchers at Chalmers University of Technology, Sweden, have developed a method that represents a breakthrough for how such supercapacitors can be produced.</b></p>​“When discussing new technologies, it is easy to forget how important the manufacturing method is, so that they can actually be commercially produced and be impactful in society. Here, we have developed methods that can really work in production,” explains Agin Vyas, doctoral student at the Department of Microtechnology and Nanoscience at Chalmers University of Technology and lead author of the article.<br /><div><br /></div> <div>Supercapacitors consist of two electrical conductors separated by an insulating layer. They can store electrical energy and have many positive properties compared to a normal battery, such as much more rapid charging, more efficient energy distribution, and a much greater lifespan without loss of performance, with regards to the charge and discharge cycle. When a supercapacitor is combined with a battery in an electrically powered product, the battery life can be extended many times –up to 4 times for commercial electric vehicles. And whether for personal electronic devices or industrial technologies, the benefits for the end consumer could be huge. </div> <div><br /></div> <div>“It would of course be very convenient to be able to quickly charge, for example, an electric car or not have to change or charge batteries as often as we currently do in our smartphones. But it would also represent a great environmental benefit and be much more sustainable, if batteries had a longer lifespan and did not need to be recycled in complicated processes,” says Agin Vyas.</div> <h2 class="chalmersElement-H2">Manufacturing a big challenge</h2> <div>But in practice, today's supercapacitors are too large for many applications where they could be useful. They need to be about the same size as the battery they are connected to, which is an obstacle to integrating them in mobile phones or electric cars. Therefore, a large part of today's research and development of supercapacitors is about making them smaller – significantly so</div> <div><br /> </div> <div>Agin Vyas and his colleagues have been working with developing ‘micro’ supercapacitors. These are so small that they can fit on the system circuits which control various functions in mobile phones, computers, electric motors and almost all electronics we use today. This solution is also called ‘system-on-a-chip’. </div> <br /><div>One of the most important challenges is that the minimal units need to be manufactured in such a way that they become compatible with other components in a system circuit and can easily be tailored for different areas of use. The new paper demonstrates a manufacturing process in which micro-supercapacitors are integrated with the most common way of manufacturing system circuits (known as CMOS). </div> <div><br /></div> <div>“We used a method known as spin coating, a cornerstone technique in many manufacturing processes. This allows us to choose different electrode materials. We also use alkylamine chains in reduced graphene oxide, to show how that leads to a higher charging and storage capacity,” explains Agin Vyas.</div> <div><br /></div> <div>“Our method is scalable and would involve reduced costs for the manufacturing process.

The electronic devices are proposed to consist of sandwiches of different layered quantum materials glued together by van der Waals interactions. Such new hybrid systems could offer new possibilities in observing correlated electronic phenomena at the interfaces and lead to applications in quantum and spintronic technologies.
