Institute Thursday Seminar
Vertical GaN power devices are promising candidates for future kV-class power electronics due to the wide bandgap and high critical electric field (EC) of GaN. Vertical architectures provide the possibility of downsizing the devices and increasing their reliability. However, still a few challenges have to be addressed such as selective area doping, Schottky contact formation and drift layer growth. In the next Thursday UNIPRESS seminar, Kacper Sierakowski from our Institute, the Crystal Growth Laboratory, will present the current state of the art in ion implantation in GaN and summarize the recent progress in the design of Junction Barrier Schottky (JBS) diodes. The Seminar “Magnesium ion implantation – key technology for GaN power electronics” will be held on Thursday, May 25, 2023 at 15:00 on Zoom platform.

Speaker: prof. Michał Leszczyński (IHPP PAS, NL-12) Title: Point defects in nitride semiconductors - do they really exist? Presence of vacancies enables atoms to move. In the seminar, the following examples of experimental data will be given: i) diffusion of indium atoms in InGaN quantum wells that leads to well homogenization and decomposition, ii) diffusion of Al atoms smearing out the AlGaN/GaN interfaces, iii) diffusion of silicon and magnesium dopants. These data were obtained during annealing with and without gallium atoms in the gas above the samples, what had a significant influence on the diffusion.
