CdZnTe (CZT) Wafer

>CdZnTe (CZT) is a new semiconductor, which enables to convert radiation to electron effectively, it is mainly used in infrared thin-film epitaxy substrate, X-ray and γ-ray detection, laser optical modulation, high-performance solar cells and other high-tech fields.

From 2001,PWAM offers commercial CZT wafers with high quality and very competitive price. We also can offer CZT crystals with contacts. Regulaly contacts of anodes and cathode are both deposited by Au, but we can use Al to the deposit the contacts as required.And we offer wafer custom size.

Zn doped CdTe, also called CZT,composition:Cd(1-x)Zn(x)Te,x=0.1( if for substrate epitaxial growth, "x" should be changed)

both sides polished
Surface roughness:<2 nm
Resistivity:  >1×10^10 Ω• cm
FWHM@59.5 keV<7%
Mu-tau value >10-3 cm2/V
EPD:<10^5 cm-2
Package: in 100 class,clean plastic bag
CZT crystal is grown by special Bridgman technique up to 30*30mm. Compared with CdTe, it has a larger band gap and excellent IR transmission. It is widely used as X-ray and gama-ray detectors, and substrate for epitaxial film.

We also provide Polycrystalline Cd0.9Zn0.1Te in the form of ingot pieces
