Sapphire (molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good heat conduction, high hardness, infrared penetration and good chemical stability. Widely used in industry, national defense and scientific research in many fields (such as high temperature resistant infrared window, etc.). At the same time, it is also a kind of single crystal substrate material with a wide range of uses. It is the preferred substrate in the blue, purple, white light emitting diode (LED) and blue laser (LD) industry at present (gallium nitride film needs to be epitaxed on the sapphire substrate first), as well as an important superconducting thin film substrate.
