Gallium oxide (Ga2O3), also known as gallium trioxide, is a wide band gap semiconductor material with high breakdown electric field strength, low theoretical conduction loss and good thermal stability, which is ideal for high pressure, high frequency and high temperature applications. In the electronics industry, gallium oxide can be used as a high-purity analytical reagent and semiconductor material preparation, widely used in display, LED, solar cells, photoelectric devices and biomedicine and other fields. In addition, gallium oxide can also be used as a single crystal substrate, making it easier for developers to develop miniaturized, efficient high-power transistors.
