Cadmium Zinc Telluride CdZnTe, (CZT, Cd1−xZnxTe) crystal is a compound of cadmium, zinc and tellurium 99.9999% or 99.99999% 6N 7N purity, shows peculiar properties in the structural properties, charge transport, contacting issues and spectrometer performance. Cadmium Zinc Telluride consists several complicated procedures of polycrystal synthesis, crystal growth for CdZnTe, post-growth treatment and substrate fabrication improvements etc, Raw material synthesis by using the technologies of gradient temperature and directional solidification, and the crystal growth technologies including High Pressure Vertical Bridgman (HPVB), Low Pressure (LPB) Vertical modified Bridgman (VB), Horizontal modified Bridgman (HB), Physical Vapor Deposition (PVD) methods, Traveling Heater Method (THM) can be employed for its promising outcomes to dissolves a polycrystalline material to produce a single-crystal , and afterwards surface treatment to remove defects and damages caused during cutting and polishing in the fabrication by chemical treatments to producing a more chemically stable surface.
Cadmium Zinc Telluride single crystal is a kind of promising photorefractive material at near-infrared wavelengths, and a wide band gap of approx 1.4-2.2 eV semiconductor for room-temperature gamma-ray spectroscopy and medical imaging. In general, It is employed for several applications such as Infrared imaging, X-ray and gamma-ray detection, optical devices, photovoltaics, solar cells, photorefractive grating, electro-optic modulator, terahertz generation, it can also be used as a substrate material for the epitaxial growth of infrared detector material-Mercury Cadmium Telluride HgCdTe.
Cadmium Zinc Telluride CZT or CdZnTe at Western Minetals (SC) Corporation can be delivered in polycrystalline state in size of granule, lump, chunk and bar or customized specification with vacuum composite aluminum bag, and in single crystal state in size of square blank 10x10mm, 14x14mm, 25x25mm or customized specification with single piece package.
