Future Prospects of CdTe Semiconductor Detectors

Abstract

  The characteristics of CdTe and CdZnTe semiconductor detectors that can be opearted at the room temperature have been evaluated. The energy resolution of each detector is much superior to that of scintillators though a little inferior to that of Ge(Li), Si(Li) or pure Ge detectors. From a practical point of view those detectors are promising and a few applications are described. The only fault at present is that they are insensitive to rather high-energy g rays. Several efforts to improve the sensitivity of them at high energy region are reported.
