Next-Generation Semiconductor Materials: Beyond SiC and GaN

Ultrawide Bandgap Semiconductors for Next Generation Power Electronics

While GaN and SiC have already taking over market shares from Si power electronics, and there are also developments ongoing to advance their performance using advanced device structures such as superjunctions to increase their breakdown voltage, there are new ultrawide bandgap materials coming into the power electronics realm, in particular Gallium Oxide and AlGaN. I will review recent advances in device technologies using this new and upcoming materials e.g. the demonstration of 4kV Gallium Oxide devices, also early reliability investigations.
