Characterization of large cadmium zinc telluride crystals grownby traveling heater method

The focus of this paper is to evaluate thick, 20 × 20 × 10 and 10 × 10 × 10 mm 3 , cadmium zinc telluride (CZT), Cd 0.9 Zn 0.1 Te , crystals grown using the traveling heater method (THM). The phenomenal spectral performance and small size and low concentration of Te inclusions/precipitates of these...

Description
Summary:The focus of this paper is to evaluate thick, 20 × 20 × 10 and 10 × 10 × 10 mm 3 , cadmium zinc telluride (CZT), Cd 0.9 Zn 0.1 Te , crystals grown using the traveling heater method (THM). The phenomenal spectral performance and small size and low concentration of Te inclusions/precipitates of these crystals indicate that the THM is suitable for the mass production of CZT radiation detectors that can be used in a variety of applications. Our result also proves that with careful material selection using IR and high-quality fabrication processes, the theoretical energy resolution limit can be achieved.
