Abstract
This gaper reviews some of the progress obtained in the understanding of de fects in detector grade cadmium zinc telluride material (CZT). Several tech niques have been utilized to elucidate some of the issues related to compos itional uniformity. effects of precipitates, grain boundaries, and surface defects related to mechanical and chemical treatments. In few cases, specia l mapping capabilities had to be developed to allow correlations with detec tor performance. (C) 2000 Elsevier Science B.V. All rights reserved.
