Cadmium zinc telluride (CZT) is a promising material for the room temperature detection and spectroscopy of ionizing radiations. Two sets of samples, exhibiting good and unacceptable performance of CZT radiation detectors, have been studied in order to resolve difference in the electrical and structural parameters which govern operational characteristics of CZT detectors. I–V, barrier capacitance, carrier lifetime, and drift velocity measurements have been combined to reveal the main differences in electrical characteristics which determine crucial difference in spectral performance of CZT radiation detectors.
