Based on the performance of gallium nitride, gallium nitride epitaxial chips are mainly suitable for high power, high frequency, and low voltage applications. It is reflected in: 1) High bandgap: High bandgap improves the voltage level of gallium nitride devices and can output higher power than gallium arsenide devices, which is especially suitable for 5G communication base stations, military radar and other fields; 2) High conversion efficiency: the on-resistance of gallium nitride switching power electronic devices is 3 orders of magnitude lower than that of silicon devices, which can significantly reduce the on-switching loss; 3) High thermal conductivity: the high thermal conductivity of gallium nitride makes it have excellent heat dissipation performance, suitable for the production of high-power, high-temperature and other fields of devices; 4) Breakdown electric field strength: Although the breakdown electric field strength of gallium nitride is close to that of silicon nitride, due to semiconductor process, material lattice mismatch and other factors, the voltage tolerance of gallium nitride devices is usually about 1000V, and the safe use voltage is usually below 650V.
