At the end of January, the team from ZDF heute journal visited the Institute for Communication Systems at RWTH Aachen University for a report. The report provides insights into the topic of “women in MINT subjects”, which are sometimes chosen even less by women and girls, such as mathematics, computer science, natural science and technology. Editor Peter Böhmer from the North Rhine-Westphalia State Studio researched the reasons for the low quota of women at RWTH Aachen University and what approaches could be taken to change this.
Through interviews with various female RWTH students, including our BA student Helena, as well as with Univ. Prof. Dr. rer. nat. Aloys Krieg, Prorector for Teaching, the heute journal team was able to gain an impression. The Institute for Communication Systems and a lecture by Prof. Peter Jax provided the pictorial framework for the report.

Honoring outstanding achievements by RWTH Aachen graduates
The Friedrich Wilhelm Prize is awarded annually by the foundation of the same name in the form of prize money to students and researchers at RWTH Aachen University who have been selected for their outstanding achiements in their theses. Among this year‘s recipients are Maxim Christian Maria Müllender, Master of Science, from the Institute of High Voltage Equipment and Grids, Digitalization and Energy Economics and Laurids Schmitz, Master of Science, from the Institute for Power Electronics and Electrical Drives. Both winners were recognized due to their excellent master‘s theses.
Funding for research and teaching
The name of the foundation goes back to the Prussian crown prince and later Emperor Friedrich Wilhelm III., who founded a polytechnic institute in the Rhine province in 1858 using a donation from the Aachen and Munich fire insurance companies. In doing so, he laid the foundation for both the Rheinisch-Westfälische Technische Hochschule and the Friedrich Wilhelm Foundation, which is founded 1865 by the legal predecessor of today‘s Aachener und Münchener Beteiligungsgesellschaft. Since then, the promotion of research and teaching and the support of students and researchers at the RWTH Aachen have been the central concerns of the foundation.
How to report and benchmark emerging field-effect transistors

One of the challenges encountered by research on novel electronic devices is to compare devices based on different materials in a consistent way. RWTH Professor Max Lemme and colleagues from USA, China, and Belgium have now proposed a set of clear guidelines for benchmarking key parameters and performance metrics of emergent field-effect transistors. The guidelines have been published as a Perspective Article in Nature Electronics.
Research on field-effect transistors (FET) has long explored the possibility of replacing silicon as channel material with emerging nanomaterials, such as carbon nanotubes, graphene, transition metal dichalcogenides, organic semiconductors, or ultrathin oxides. The field is thriving and keeps uncovering fundamental aspects of these materials. But when it comes to comparing the performance of different devices, there is often a lack of consistent reporting and benchmarking
“Assessing consistently the potential of new materials for novel transistors is difficult, because the performance depends on many aspects and details of the device structure, and many parameters are interdependent.” explains Prof. Lemme. Further complexity is added to the field by the interdisciplinarity of the research community, which includes electrical engineers, chemists, materials scientist and physicists. The multitude of approaches increases the challenge of reporting and benchmarking results consistently.
To address this situation, Lemme and colleagues have prepared a checklist of device parameters to be reported, as well as a list of recommended benchmarking plots to compare device parameters and performance metrics. In addition, they present an explicit example of how to use the proposed procedure by applying it to the case of FETs based on monolayer molybdenum disulfide (MoS2), which is one of the emerging materials most studied in recent years for transistor application.
“To identify the real advantages and opportunities offered by novel materials in the search for improved transistors, we need to be able to benchmark and report different devices in a consistent way. We also need to make sure that all relevant data are reported every time.” adds Lemme. “We hope that our work will contribute to bring clarity in the community and guide the search for even better devices.”

RWTH student team AixSense successful in international SensUs competition
The Faculty of Electrical Engineering and Information Technology warmly congratulates students Daniyar Kizatov, Jiayi He, Anshul Prashar and Shunjiro Sodei and all involved on their successful second place in the international Biosensor Competition SensUs! The fourth generation of the RWTH Aachen student team AixSense participated in the SensUs competition at Eindhoven University of Technology this year.
Consisting of four ambitious students from the fields of Computer Engineering and Micro-Nano-Electronics, the interdisciplinary team has spent the past six months developing a prototype biosensor to detect the influenza A virus. Thus, the team worked in the laboratories and clean rooms of our Institute of Materials in Electrical Engineering 1 at RWTH, where the chips (see picture on the right) were produced as key components for the technology. The team was supervised by Prof. Sven Ingebrandt and Dr. Vivek Pachauri.

At the final event, the AixSense team presented the biosensor prototype and was awarded in four categories for analytical performance, creativity, transferability of the concept and public inspiration. In the Analytical Performance category, RWTH Aachen University took second place by a slight margin.
“Our team was never so close to winning one of the most important awards. It was very close and we are proud of our performance.”
– Daniyar Kizatov, team leader of AixSense
This year, 14 student teams from Denmark, Egypt, the Netherlands, Germany, Portugal, Switzerland, China, Sweden, the USA, Belgium, the UK, Canada and Spain took part in the competition.
The biosensor has been known to the public at the latest since the introduction of the Covid rapid test – but the SensUs community has been supporting young scientists to present their research in the field of biosensors internationally for five years. Every year, a new generation of teams faces the challenge of developing a biosensor prototype for a new disease. So far, the focus has been on detecting biomarkers for kidney failure, heart failure, antibiotic resistance, rheumatism and epilepsy.
Next year, the SensUs competition aims to detect cytokines as crucial proteins in the immune system. The application phase for the next generation of the AixSense team starts in December 2021 – more information on how to apply can be found here.

Competence Cluster Battery Utilization Concepts (BattUtilization)
Copyright: ISEA
With the further spread of renewable energies and electromobility, powerful and reliable energy storage systems are becoming increasingly important. When is the secondary use of battery storage possible and for which applications is it useful? This question is being addressed by the project partners from research and industry in the new Battery Utilization Concepts ( BattNutzung) cluster, which is being funded by the German Federal Ministry of Education and Research with around 20 million euros. The cluster is coordinated by Prof. Sauer from ISEA. Together with the competence cluster greenBatt, the BattNutzung cluster forms the cross-sectional initiative “Battery Life Cycle”. This aims at a holistic view of second use and recycling concepts, which is to be enabled by linking the two clusters and through a cross-cluster exchange.
