Cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) offer great promise as x-rayand gamma ray detectors. Due to the high detection efficiency, the good room temperatureperformance and the recent improvements on crystal growth technology, CdTe and CdZnTedetectors have obtained an increasing interest in the field of hard x-ray and gamma rayastronomy. In this paper, we report on the R&D activities on CdTe and CdZnTe detectors forhigh energy space instrumentation. Our group has been involved in the design of new multilayerhard x and soft gamma ray Laue lens telescopes and, in particular on the development of focalplane detectors based on CdTe and CdZnTe. Here we present the activities carried out on thesedetectors for the evaluation of imaging, spectroscopy and polarimetry performances in the hardX and soft gamma ray energy range.
