Abstract

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.

太赫兹光电探测器二维材料的最新进展

太赫兹（THz）波以其穿透性好、安全性高、相干性好、带宽大等优点，在第六代通信技术、生物医学、光谱学、无损检测、安全检测等领域具有巨大的应用潜力。目前，太赫兹光电探测器的研究热点是向宽带响应、小型化、高灵敏度、低噪声和室温工作方向发展。基于石墨烯、黑磷、过渡金属二硫化物和拓扑半金属等二维（2D）材料的太赫兹光电探测器引起了研究人员的极大关注。本文主要讨论了这四种材料在太赫兹光电探测器应用中的最新研究进展。
