Gallium oxide is a wide bandgap semiconductor with a bandgap width Eg=4.9eV. It has good electrical conductivity and luminescence properties. Therefore, it has broad application prospects in optoelectronic devices and is used as an insulating material for Ga-based semiconductor materials in Chemicalbook. layers, and UV filters. These are the traditional application fields of gallium oxide, and its future power, especially high-power application scenarios, is more worth looking forward to.
