Sapphire Wafers

Due to the less mismatched lattice and stable chemical and physical properties, sapphire(Al2O3) wafer is the popular substrates for III-V nitrides, superconductor and magnetic epi-film. They are widely used in GaN and thin-film epitaxial growth, silicon on sapphire, LED market and optics industry.
