Abstract
|
|
|
|
As a photoconductive material with a high X-ray sensitivity, many researches about mercury iodide has been carried out to substitute for amorphous selenium. However, it has many limitations in commercialization because of the high leakage current. In this study, we fabricated HgI 2 unit-cells with mixed silicon oxide(SiO 2 ) and titanium oxide(TiO 2 ) to reduce a high leakage current and we evaluated an electrical properties of the fabricated unit-cells. As a result, we confirmed that both mixtures were effective in reduing the leakage current of the HgI 2 and x-ray sensitivity were significantly increased in fabricated HgI 2 -TiO 2 unit-cell.
