AII-BVI Compounds: CdZnTe

Description

CdZnTe is a ternary compound of cadmium, zinc, and tellurium, with the chemical formula Cd1-xZnxTe. It is a semiconducting material that is commonly used as a radiation detector, particularly in medical imaging and security applications. CdZnTe is valued for its high detection efficiency, high resolution, and high speed. It has a wide bandgap, which allows it to detect high-energy radiation, and can be grown as large single crystals, making it suitable for use in large-area detectors.
