CdZnTebased

CdZnTe, also known as Cadmium Zinc Telluride, is a semiconductor alloy material with the chemical formula Cd x Zn 1-x Te. The properties of CdZnTe can be tuned by varying the composition, represented by the mole fraction x. This material is a solid solution of cadmium telluride (CdTe) and zinc telluride (ZnTe). CdZnTe is a direct bandgap semiconductor, meaning that its electronic properties are well-suited for optoelectronic applications. Its bandgap can be adjusted by changing the ratio of cadmium to zinc, typically ranging from approximately 1.5 eV for pure ZnTe to 1.44 eV for pure CdTe at room temperature. The ability to tune the bandgap makes CdZnTe a versatile material for various technological uses.

CdZnTe is widely recognized for its excellent performance in radiation detection, particularly for gamma rays and X-rays. Its high atomic number for both cadmium and tellurium, combined with its relatively wide bandgap, results in high detection efficiency and good energy resolution. This makes it a preferred material for applications in medical imaging, such as computed tomography (CT) scanners and positron emission tomography (PET) systems, as well as in security screening and nuclear physics research. Furthermore, CdZnTe has been explored for photovoltaic applications, with efforts to create efficient solar cells by tuning its bandgap to match the solar spectrum. Its semiconductor properties also lend themselves to potential uses in infrared detectors and other electronic devices.
