Semiconductor detectors typically identify gamma radiation sources. Semiconductor detectors using Cadmium Zinc Telluride (CZT) to detect x-rays and gamma rays. CZT is a room-temperature semiconductor that directly converts x-ray or gamma-ray photons into electrons; the radiation deposits energy at some point in the crystal lattice where it results in the generation of pairs of charge carriers. By application of an electric field, the charge carriers get swept to the cathode and anode of the device where they induce a current pulse that can be detected.
