Detection Principles of Wide Bandgap Semiconductor Nuclear Radiation Detectors
摘要
Semiconductor materials have a rapid pulse rise time, which is vastly superior to the radiation resisting ability of gas media and vastly lower than the average ionization energy of gas media. As a result, semiconductor detectors have excellent energy resolution, a wide energy linear range, a rapid time response, and a small size, among other benefits. Since the 1960s, when semiconductor materials began to be used as radiation detection media, semiconductor detectors have been widely used in a variety of radiation detection fields.
