Panel discussion

GaN is already now the material of choice for power conversion up to 650 V. Despite a similar breakdown field as SiC, GaN is not compatible for higher voltages up to 10 kV. The figures of merit predict a really strong performance with experimental results lagging. In the rump session, we will discuss what is currently limiting the performance of GaN based power electronics and how to overcome these limits. Additionally, the nitride family also offers a wider range of materials, e.g., AlGaN and AlN with even wider band gaps with breakdown fields surpassing SiC and even diamond. Theoretically these materials could be the next generation semiconductors for power electronics. We will critically discuss the actions that need to be taken to align theoretical expectations with experimental results.<br><br>Panelists include experts in GaN power devices, native substrate growth and preparation, AlGaN and AlN power electronics as well as an intimate knowledge of the industry and their requirements for a successful transfer into the market.
