太赫兹波具有瞬态性、宽带性、穿透性和低能性等一系列独特性质, 使其在材料研究、信息传递、环境检测、**安全、医疗服务等方面展现了非常广阔的应用前景。作为该领域应用的关键, 太赫兹探测器得到科研人员极大的重视。一般来讲, 探测器的性能很大程度上依赖于基质材料的特性。石墨烯具有2个非常重要的优势, 一是石墨烯具有线性能带结构, 使得能够吸收太赫兹波；二是石墨烯具有超高载流子迁移率, 能够进行超快探测。因此, 石墨烯基有望成为太赫兹频段新一代高性能探测器的基质材料。详细综述了近几年关于石墨烯基太赫兹探测器的发展状况。

Terahertz wave has unique advantages, such as being transient, broadband, penetration and low energy, which shows a very broad application prospect in the research of materials science, information communication, environmental monitoring, national defense, medical services etc. As the key of the application in this field, terahertz detector has attracted much attention. Graphene has two advantages for detector. Firstly, the linear band structure makes it possible to absorb terahertz photon and convert to current or voltage. Secondly, it has ultra high carrier mobility so that it could realize ultrafast detection. Therefore, graphene is expected to be the suitable material for new generation of high performance detectors in the terahertz band. The development of terahertz detectors based on graphene in recent years is summarized in detail.
