Abstract

High-quality CdZnTe (CZT) films were fabricated using the radio frequency magnetron sputtering technique. Ultraviolet (UV) photodetectors based on CZT films were fabricated with gallium-doped zinc oxide (GZO) and gold electrodes. The electrodes and film thickness on the performance of CZT film UV photodetectors was studied. The results indicate that GZO electrodes can form good ohmic contact with CZT, thereby enhancing the sensitivity and response of CZT photodetectors. An increase in film thickness improves the film quality, resulting in enhanced performance of CZT film UV photodetectors.
