Recent trends in the development of CdTe and CdZnTe semiconductor detectors for astrophysical applications
2010
Cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) offer great promise as x-ray and gamma ray detectors. Due to the high detection efficiency, the good room temperature performance and the recent improvements on crystal growth technology, CdTe and CdZnTe detectors have obtained an increasing interest in the field of hard x-ray and gamma ray astronomy. In this paper, we report on the R&D activities on CdTe and CdZnTe detectors for high energy space instrumentation. Our group has been involved in the design of new multilayer hard x and soft gamma ray Laue lens telescopes and, in particular on the development of focal plane detectors based on CdTe and CdZnTe. Here we present the acti…
Progress in the Development of CdTe and CdZnTe Semiconductor Radiation Detectors for Astrophysical and Medical Applications
2009
Over the last decade, cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) wide band gap semiconductors have attracted increasing interest as X-ray and gamma ray detectors. Among the traditional high performance spectrometers based on silicon (Si) and germanium (Ge), CdTe and CdZnTe detectors show high detection efficiency and good room temperature performance and are well suited for the development of compact and reliable detection systems. In this paper, we review the current status of research in the development of CdTe and CdZnTe detectors by a comprehensive survey on the material properties, the device characteristics, the different techniques for improving the overall detector…
