Development of X-ray Detectors Based on Wide-bandgap Semiconductor
摘要
Abstract
High-performance semiconductor X-ray detectors prefer outstanding characteristics including low detec-tion of limit,low dark current,high sensitivity,fast response time,high radiation hardness and so on.Wide-band-gap semiconductors such as silicon carbide(SiC),gallium nitride(GaN),diamond,gallium oxide(Ga2O3),and zinc oxide(ZnO)exhibit exceptional properties,including a wide bandgap,high electron mobility,high breakdown field strength,high saturated carrier drift velocity,and large displacement energy.These characteristics enable them to demonstrate superior performance in X-ray detection,meeting the requirements for high-performance semiconduc-tor X-ray detectors and making them highly promising candidates for such applications.As a result,they have emerged as promising candidates for advanced X-ray detectors.In this paper,the electrical properties,preparation technology and detection performance of SiC,GaN,diamond,Ga2O3,ZnO X-ray detectors are introduced,and the latest research is discussed.Meanwhile,future research directions and potential applications of wide-bandgap semi-conductor X-ray detectors in medical imaging,industrial detection and space exploration conduct in-deep thinking.关键词
