Cadmium telluride (CdTe) is a stable crystalline compound composed from cadmium and tellurium. Doped with a small amount of Zn it produces cadmium zinc telluride, (CdZnTe) or CZT.
CdTe and CdZnTe pixel detectors are implementing in imaging systems which are widely used in medical diagnostics (mammography, dental phantoms), astronomy, and industrial research.
CdTe and CdZnTe pixel detectors are very appealing due to their high energy resolution at normal conditions which is not high enough in currently implementing materials [4, 1]. Another advantage of those detectors is their perfect efficiency while working with X-ray energy spectrum as well as compatibility with gamma rays, alpha and beta particles [5, 3].
Nowadays, there are two ways of using CdTe/CZT detectors. The first one is focused on single channel detectors which are used in X- and gamma- ray spectroscopy. The second is proposed for multi-channel devices in nuclear medicine mostly. [5, 26]
