Gallium nitride, GaN substrate. GaN has a wide direct bandgap, strong atomic bonds and high thermal conductivity, etc., and it is a strong ability on anti-radiation, Not only is the short-wavelength optoelectronic materials, Also the replacement materials of high temperature semiconductor device, GaN can be used to make blue and green LED, or violet, ultraviolet light LD, ultraviolet detectors and high-frequency high-power electronic devices.
