5. IKZ Winterschool


The winterschool will be a face-to-face event with opportunities for networking and possibility to visit the IKZ and its researchers. It will be held in English. For interested people that cannot attend we will broadcast the lectures to registered participants via Zoom.

This event is a cooperation between the Leibniz-Institut für Kristallzüchtung (IKZ) and the Fraunhofer Institute for Integrated Systems and Device Technology IISB


Max-Born-Str. 2 A
12489 Berlin


The winterschool will be not affected by the announced strike of Berlin's public transport. Trains and S-Bahn are running, and you can reach Berlin-Adlershof station (800 m walk from winterschool site) from both the railway and flight terminals by S-Bahn running at least every 10 minutes (except 1am to 4am).


About the Topic

Energy transition for climate protection triggers a booming need for advanced power electronics; energy efficient power conversion is needed on all different power levels. The IKZ Winter School aims to provide an overview of existing a& upcoming materials and technology platforms (Float Zone Si, SiC, GaN, AlN , Ga2O3, Diamond).

The school is intended for master & PhD students as well as PostDocs with interest in materials science and device technology as well as industry researchers, developers and manages in the field. Internationally renowned speakers from academia and industry will present and discuss with you their fields of expertise.
