Ga2O3 is a member of the ultra-wide bandgap semiconductor family. Because of its wide bandgap, it finds applications in UV-transparent conductive films, UV detectors, and high power electronics and possibly in microwave switching and amplification. Power electronics applications range from on-chip power converters to high voltage rectifiers for electric power transmission lines. High-voltage switching transistors used in these applications are required to have small ON resistance while providing very high blocking voltages in the OFF state. There are already kV-range power switches today. The target for the Ga2O3 devices will be in the 100s of kV to MV range.
