Abstract

Data obtained with BNL's National Synchrotron Light Source (NSLS) has helped to elucidate, in detail, the roles of non-uniformity and extended defects on the performance of CZT detectors, as well as the root cause of device polarization during exposure to a high flux of incident X-rays. Measurements of carrier traps will be reported, including their nature and relationships to different growth methods (conventional Bridgman, high-pressure Bridgman, traveling heater, and floating zone methods). Most findings will be correlated with the performance of spectrometer-grade CZT Xray and gamma detectors, and new directions to resolve the material deficiencies will be offered.
