摘　　要：太赫兹波独特的性质使其在物理学、生物学、医疗诊断、无损检测、无线通信等领域有着广阔的应用前景。共振隧穿二极管(RTD)是一种基于量子隧穿效应的半导体器件,利用其负微分电阻和直流非线性特性,可以分别实现太赫兹波的产生和探测,近年来获得越来越多的关注。基于RTD的太赫兹探测器具有可室温工作、体积小、易集成、灵敏度高等特点,使其在未来短距离、超高速的太赫兹无线通信及万物互联等场景具备优势。本文将重点介绍太赫兹RTD探测器的研究进展及其应用进展,并对后续技术发展进行展望。Terahertz technology has important application prospects in the fields of physics,biology,medical diagnosis,non-destructive testing,and wireless communication.As an excellent candidate for both terahertz oscillator and detector,Resonant Tunneling Diode(RTD)has received increased attention in recent years.RTD is a semiconductor device based on the quantum tunneling effect,which simultaneously provides a negative differential resistance and nonlinear current-voltage characteristics.As for detector,it has distinct features of room-temperature operation,small size,easy integration,and high sensitivity,which makes it particularly suitable for applications scenarios such as short-range,ultra-high-speed terahertz wireless communication and the internet of things.This review focuses on recent progresses and applications of terahertz RTD detectors,and aims to provide further perspective on it.
