Surface effects play an important role in the overall performance of X-ray detector. The effects of passivation with (NH4)(2)S on semi-insulating polycrystalline CdZnTe thick films were analyzed with X-ray photoelectron spectroscopy (XPS), photoconductive decay (PCD), noise power spectrum and pulse height spectra measurements. Sulfur passivation with (HN4)(2)S effectively removes the Te-oxide layers on the CdZnTe surface, reduces the surface leakage current and gives higher energy resolution by suppressing 1/f noise.
