The Cd0.96Zn0.04Te (CZT) is the preferred material using as a substrate, mainly due to its similar lattice constant to HgCdTe (MCT), transparency to infrared (IR) wave lengths to be detected by the MCT layer, as well as the excellent electrical properties, high absorption coefficient and moderate thermal expansion.
