Fiscal Year: 2001
Title: Development of Large Size and Low Cost Cadmium Zinc Telluride Single Crystals for Improved Room Temperature Radiation Detectors used for National Security
Agency: DOE
Contract: DE-FG02-00ER83129
Award Amount: $0.00
 

Abstract:

60972 Cadmium Zinc Telluride (CdZnTe) is an important material for detectors used for national security. However, the production of CdZnTe, dominated by the High Pressure Bridgman technique for a decade, has suffered from low-yields (1-4%) and small device sizes (1-3 cm3). This project will develop an alternative Modified Vertical Bridgman, CdZnTe crystal growth technique with higher yield and larger-sizes, leading to higher volume detectors which are not available today. In Phase I, 50 cm3 large-size single CdZnTe crystals were produced with a high yield of over 50%. The crystals demonstrated an unprecedented mobility-lifetime product for electrons without compromising bulk resistivity. The pixellated and co-planar grid detectors performed with excellent energy resolutions. In Phase-II, a 3¿ diameter growth technique will be developed. Commercial Applications and Other Benefit as described by the awardee: These large-size single crystals, coupled with higher yields of CdZnTe single crystals should lower costs and further improve detector performances, especially for high-resolution room temperature radiation detectors with low-cost for national security and nuclear medicine
