Award for best student poster presentation at IWN 2022
(14 Oct. 2022)

Congratulations to our PhD student Sondre Michler (Siltronic) for winning a best student poster presentation award during his very first conference at IWN 2022! Sondre presented a model that can be used to predict wafer curvature during and after epitaxy. In turn, the model can provide additional valuable information about stress engineering in vertical GaNon-Si(111) devices. The poster showed the validation of the model based on experimental data and how predictable changes can be made to the buffer to tailor the stress build-up in the complete layer-stack.

Award for presentation at the SSIE summer school in Brixen
(15 July 2022)

Our PhD student Youssef Hamdaoui (CNRS, ULille and UGent) won the second best presentation award at the SSIE summer school in Brixen. His presentation describes the current status and related results of his PhD thesis dealing with the optimization of quasi-vertical Schottky diodes and the transition to fully vertical GaN-on-silicon devices through the development of the backside contacts, which led to the demonstration of first fully vertical Schottky diodes. Congratulations Youssef! What a great start of your scientific career.

YESvGaN is presenting on the SSIE Summer School in Brixen
(11-15 July 2022)

“Brixen has heard we are present on the SSIE summer PhD school! Five of the lectures were given by YESvGaN partners: AIXTRON, CNRS, IISB, Bosch and IUNET.

YESvGaN-related article paper (08 June 2022)

A portable charger for electric cars offers several advantages for our green future. The latest publication of Ditze et al. (IISB) demonstrates a compact and highly efficient prototype. The article is available as open access article: https://www.mdpi.com/2079-9292/11/12/1818

YESvGaN-related article paper (06 June 2022)

An article on resonant push-pull DC-DC converters suitable for switching frequencies in the MHz-range was published by Weitz et al. (Friedrich-Alexander-University Erlangen-Nuremberg in cooperation with the project partner Fraunhofer-IISB) on the IEEE Transactions on Power Electronics. The article is available as open access article under: https://ieeexplore.ieee.org/document/9681301

3rd YESvGaN project meeting at Bosch in Renningen, Germany
(01/02 June 2022)

After one year of hard work, the YESvGaN consortium finally met in real life! The first day an update of all work packages was given, showing that despite all challenges we are gradually advancing towards the industrialization of vertical GaN membrane transistors. The presentations were followed by a poster session by all partners showing the expertise of many partners is complementary which makes this project into a great success.
At the second day, face to face technical sessions were organized. After this we all went home with a satisfied feeling. Thank you to Bosch to organize this meeting in Renningen. We are looking forward to see everyone again soon!

YESvGaN M6 meeting 04 November 2021 (held online)

The YESvGaN consortium met online on the 4th of November. In the first part of the meeting, the status of the different work packages was presented and the upcoming challenges were discussed. The second part of the meeting was used to elaborate on the technical details of some of the key results. In general, the project status is considered to be very good despite the difficult conditions caused by COVID-19.

We want to thank all partners for their contributions! We are looking forward to once see all those happy faces in real-life!
