Cadmium-zinc-tellurium crystals (CdZnTe)
Cadmium-zinc-tellurium (CdZnTe) is a material for detectors and ionizing radiation spectrometers working at room temperature.
Solid solution crystals are semiconductor material which properties allow to use it for gamma-ray detection while radiation monitoring and spectroscopy, in medical devices, dosimetry and environmental control, as well as in astrophysics and space technology.
