Abstract

Various types of Cd_1-xZn_xTe (0.04 < X < 0.24) detector crystals grown by vertical high pressure Bridgman (VHPB), low pressure Bridgman (LPB) i.e. vertical ambient pressure Bridgman (VB), horizontal ambient pressure Bridgman (HB) and vapor grown crystals have been evaluated and compared. We have used the following methods in order to evaluate the CZT: (1) Triaxial crystal x-ray diffraction (TAD) for determination of the surface crystalline homogeneity, (2) Nuclear spectroscopic response of detectors and (3) Sensitivity to radiation from high flux x-rays for investigations of the suitability for x-ray digital imaging. Finally a comparison between the various methods of CZT crystal growth will be given.
