Ga2O3 substrate

Gallium oxide (Ga2O3) single crystal is a wide-bandgap semiconductor material.  Gallium oxide (Ga2O3) has broad application prospects in optoelectronic devices, it used as an insulating layer for Ga-based semiconductor materials, and as an ultraviolet filter.
There are five crystalline phases of Ga2O3, but beta-Ga2O3 is the only one that can exist stably at high temperature. β-Ga2O3 is a new type of ultra-wide bandgap transparent semiconductor material with a forbidden band width of about Eg=4.8 eV, which suitable for manufacturing high power vertical structure power devices with high current density. It has application prospects in the fields of ultraviolet detectors, light-emitting diodes (LEDs) and gas sensors.
