 Gallium oxide, GA-203, is an emerging wide bandgap semiconductor that has attracted a large amount of interest due to its ultra-large bandgap of 4.8EV, a high breakdown field of 8MV slash CM, and high thermal stability. These properties enable a promising material for a large range of applications such as high-power electronic devices and solar-blind ultraviolet UV photo detectors.
