Gallium oxide, as a new type of ultra-wide bandgap semiconductor, is expected to be used in power electronics and solar blind UV photodetectors. The main cause of research and development onβ-Ga2O3 is inspired by its larger bandgap, higher breakdown field, bigger Baliga figure-of-merit (FOM), shorter absorption edge and lower cost comparedto the third-generation semiconductors, such as SiC and GaN.
