More info

Mercury Cadmium Telluride (also cadmium mercury telluride, MCT, MerCad Telluride, MerCadTel, MerCaT, or CMT) is a chemical compound of cadmium telluride (CdTe) and mercury telluride (HgTe) with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions. It can be ‘tuned’ to the desired IR wavelength by varying the cadmium concentration. Heeger Materials offers a selection of over 100 high-purity products, including metals, metal oxides, and metal salts, with 99.999% purity or higher.
