AlN Single Crystal Substrate Description

AlN Single Crystal SubstrateAlN Single Crystal Substrate has the advantages of a wide bandgap, high breakdown electric field, high thermal conductivity, high electron saturation rate, and high radiation resistance. It has a bandgap of 6.2eV and a direct bandgap, which is an important blue and ultraviolet light-emitting material. It has high thermal conductivity, high melting point, high resistivity, strong breakdown field, and low dielectric coefficient. It is an excellent electronic material for high temperature, high frequency, and high-power devices. AlN oriented along the c-axis has very good piezoelectricity and high-speed propagation properties of surface acoustic waves, and is an excellent piezoelectric material for surface acoustic wave devices.
