Machine learning for efficient battery use in mobility and energy supply for sustainable climate protection
In the fight against climate change, batteries play a crucial role as a flexible energy storage system for renewable energies. However, battery ageing during use is proving to be the limiting factor for an efficient and reliable future energy system. In this work, machine learning enables online ageing diagnosis, prediction of future ageing progression and optimisation of operation strategy, which not only increases battery performance and lifetime, but also reduces unexpected failures and contributes to more transparency about battery health. The methodology developed improves battery use in mobile and stationary applications, enabling safer and longer-lasting operation, which saves costs in the long term, conserves resources and is socially feasible. This work thus provides an essential building block for the broad acceptance and implementation of climate-friendly mobility and energy supply on the way to a climate-neutral energy system.

We would also like to congratulate Dr. Lars Nolting from the Chair of Energy System Economics at RWTH Aachen University on winning the first prize, as well as all the other prize winners:
Dr. Manuel Häußler from the University of Konstanz, Dr. Kim Teppe from the University of Hamburg, Dr. Julia Böcker from the University of Lüneburg, Dr. Mareike Trauernicht from the Free University of Berlin and Dr. Felix Lansing from the Technical University of Dresden.

Healing Achilles heel of two-dimensional transistors

Stability – in the sense of stable operation thorough lifetime – is one of the key characteristics that an electronic device need to present to be suitable for applications. And it is the Achilles heel of transistors based on two-dimensional materials, which typically show much worse stability than devices based on silicon. A team of researchers from TU Wien, AMO GmbH, RWTH Aachen University and Wuppertal University has now demonstrated a novel engineering approach to enhance the electrical stability of two-dimensional transistors by carefully tuning the Fermi energy. The results have been reported in Nature Electronics.

Today, there is little doubt that devices based on graphene and other two-dimensional (2D) materials can exceed the state of the art for certain applications, thanks to their intrinsic properties. Two-dimensional materials are also seen as some of the most promising candidates for realizing ultimately scaled transistors at the end of the roadmap of silicon technology.  However, devices based on 2D materials often show poor electrical stability, meaning that their behavior changes depending on their operation history.

“Component reliability is one aspect that is often neglected in research. This is precisely where we have been working for several years, because it is of central importance for applications.” explains Professor Max Lemme, scientific director of AMO GmbH and Head of the Chair of Electronic Devices at RWTH. The instability is not only caused by 2D materials themselves, but mostly by charges trapped into the oxide-insulator used to fabricate the transistors. “Ideally, one would like to use a different insulator with fewer charge traps,” says Lemme, “but there are no scalable solutions for this yet. In our work, we have shown instead that it is possible to use a standard insulator such as aluminum oxide and to significantly suppress the adverse effects of the charge traps in the oxide, by adjusting the charge carrier density in the 2D material.”

The work combines a thorough theoretical analysis of the novel approach – dubbed by the authors ‘stability-based design’ – and a proof of principle demonstration of the concept, performed by measuring different types of graphene-based FETs. The key idea of the approach is to try to engineer the combination 2D-material/insulator in such a way that the energy of the charge traps in the insulator is as different as possible from the one of the charge carriers in the 2D material. Lemme explains: “Graphene based FETs were the ideal test bed for our approach, as it is relatively easy to tune the energy of charge carriers in graphene. The approach, however, is applicable to all FETs based on 2D semiconductors”.  These results represent a major step forward towards stable and reliable 2D materials transistors to be integrated in semiconductor technology.

From 1 to 21 June, the CITY CYCLING competition goes into the next round. The aim of the competition is to use the bicycle as often as possible within the 21 days and thus not only to make a contribution to climate protection, but also to ensure a better quality of life in the municipalities.

The CITY CYCLING campaign contributes making cycling more present in public discourse and supports the targeted improvement of cycling infrastructure. The routes tracked by app during CITY CYCLING are evaluated anonymously by “Technische Universität Dresden” and the results are passed on to the municipalities.

Who can participate?
CITY CYCLING is intended for everyone. Regardless of whether the bicycle is already used as the main means of transport or spends most of its time in the basement. Every kilometre cycled counts. Even more so if it would otherwise have been covered by car.

The Faculty of Electrical Engineering and Information Technology is taking part in this campaign and has founded the team “Fakultät für Elektrotechnik & Informationstechnik”. To join the Faculty team, registration is required. You can join our team until the last of the 21 CITY CYCLING days.

The kilometres covered can either be entered online in the km-book or tracked via the CITY CYCLING app (Android and iOS). But participation is also possible without internet access. In this case, cyclists can report their cycling kilometres weekly to the local CITY CYCLING coordination via a kilometre log sheet.

Even though it is primarily about promoting cycling and protecting the environment, there are also prizes to be won, among others, for the most active municipalities and municipal parliaments.

For more information, feel free to take a look at the CITY CYCLING website.

We look forward to your participation!
