InAs single crystal is widely used as the substrate material for heterojunction materials (InAsSb/In－AsPSb,InNAsSb) which is used in making infrared emitting devices with 2～14μm. InAs can also use as a substrate material for the epitaxial growth of AlGaSb- superlattice structure materials for medium wave infrared quantum cascade laser(QCL). InAs is widely used in gas monitoring, low loss optical fiber communication. With high mobility Ratio, it is an ideal material for Hall semiconductors. As one kind of single crystal substrate, InAs must have low dislocation density, good lattice integrity, appropriate electrical parameter and high homogeneity. The mainly growth method of this material is classical liquid encapsulation pulling method(LEC).
