Abstract

Recently, the compound materials(a-Se, HgI₂, PbO, CdTe, PbI₂, etc.) that are used in flat panel x-ray imager have been studied for digital x-ray imaging. In this paper, the signal detection properties of HgI₂ and a-Se conversion layer, are compared. The thick HgI₂ film is fabricated by special particle-in-binder method and the conventional vacuum thermal evaporation is used for a deposition of a-Se film. And an electrical characteristic measurements were investigated about leakage current, signal response property and x-ray sensitivity. From the experimental results show that the HgI₂ film has a low operation voltage and high signal generation than that of a-Se.
