As a substrate, indium arsenide InAs single crystal substrate can not only grow InAsSb / in aspsb, innassb and other heterojunction materials, but also be used to fabricate infrared light-emitting devices with wavelength range of 2-14 μ m, epitaxial growth of AlGaSb superlattice structure materials, and fabrication of mid infrared quantum cascade lasers. Infrared light-emitting devices and infrared lasers have very good application prospects in gas monitoring, low loss fiber communication and other fields. InAs single crystal has high electron mobility and is also an ideal material for Hall devices.
