Telluride Chemical

CAS No   1304-82-1

Application / Uses Preparation
Bismuth telluride (Bi2Te3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth(III) telluride. It is a semiconductor which, when alloyed with antimony or selenium is an efficient thermoelectric material for refrigeration or portable power generation. Topologically protected surface states have been observed in Bismuth telluride.

CAS No   1306-25-8

Application / Uses Preparation
Cadmium telluride (CdTe) is a crystalline compound formed from cadmium and tellurium. It is used as an infrared optical window and a solar cell material. It is usually sandwiched with cadmium sulfide to form a p-n junction photovoltaic solar cell. Typically, CdTe cells use a n-i-p structure.

CAS No   1315-11-3

Application / Uses Preparation
Zinc telluride is the chemical compound with the formula ZnTe. This solid is an intrinsic semiconductor material with band gap of 2.23–2.25 eV. It is usually a P-type semiconductor. Its crystal structure is cubic, like that for sphalerite and diamond.
