Cd1-xZnxTe gamma ray detectors

Results of an effort to improve the performance of CdTe detectors by addressing starting element purity and crystallinity are described. Structural perfection was improved by alloying with ZnTe to form crystals of Cd/sub 1-x/Zn/sub x/Te. Crystals were grown by a high-pressure Bridgman method. Eviden...

Zusammenfassung:Results of an effort to improve the performance of CdTe detectors by addressing starting element purity and crystallinity are described. Structural perfection was improved by alloying with ZnTe to form crystals of Cd/sub 1-x/Zn/sub x/Te. Crystals were grown by a high-pressure Bridgman method. Evidence for significant enhancements of the mu tau products resulting from these efforts is presented. Features of Cd/sub 0.8/Zn/sub 0.2/Te detectors include energy resolutions at 122 keV
