摘　　要：Terahertz(THz)waves have great application potential in the sixth-generation communication technology,biomedicine,spectroscopy,non-destructive testing,security inspection and other fields due to their advantages of good penetration,high safety,good coherence,high bandwidth and many other merits.At present,the research hotspots of THz photodetectors are developing towards broadband response,miniaturization,high sensitivity,low noise and room temperature operation.Terahertz photodetectors based on two-dimensional(2D)materials such as graphene,black phosphorus,transition metal dichalcogenides,and topological semimetals have attracted amazing attention for the researchers.This paper mainly discusses the recent research progress of these four types of materials in the application of terahertz photodetectors.太赫兹波因具有强穿透性、高安全性、强相干性、高带宽等诸多优点,在第六代通信技术、生物医学、光谱学、无损检测、安全检查等领域有着巨大的应用潜力.目前,太赫兹光电探测器的研究热点正朝着宽谱响应、小型化、高灵敏度、低噪声和室温工作等方向发展.基于石墨烯、黑磷、过渡金属硫族化合物、拓扑半金属等二维材料的太赫兹光电探测器备受科研人员的关注,本文重点综述了这四类材料在太赫兹光电探测器领域应用中的研究进展.
