Semiconductor detector

A device which detects gamma rays by means of the induced charge displacement in a semiconducting material, e.g. Ge, cadmium telluride (CdTe) or cadmium zinc telluride (CdZnTe). Semiconductor detectors are characterized by good energy resolution but some (e.g. Ge detectors) require cooling with liquid nitrogen.
