摘要：

The x-ray sensitivity of a-Se films (similar to 130 mu m) as a function of combinational doping, i.e. chlorine (similar to 5 to 40 ppm) and arsenic (similar to 0.15 to 0.35%, by weight) has been studied using the potential decay technique. The films doped combinationally with similar to 30 ppm chlorine and similar to 0.30% arsenic show the maximum sensitivity. This has been attributed to the optimum combinational and complementary roles played by the two dopants, i.e. the mobility enhancement role of chlorine and charge sustaining role of arsenic.
