摘要
石墨烯因其高载流子迁移率和宽光谱吸收范围而广泛应用于光电探测.然而,其低光吸收率导致的高暗电流严重限制了它的光电探测性能.钼基二硫族化合物(MoX2,X=S、Se和Te)具有高的吸收系数,能够弥补石墨烯基光电探测器中暗电流较高的劣势,因此基于石墨烯/MoX2 范德华异质结的光电探测器能够表现出优异的光电子特性.本综述首先回顾了光电探测器的工作原理、性能指标和结构.之后,从材料基础的角度突出了石墨烯/MoX2 范德华异质结光电探测器的重要性.接着,总结了石墨烯/MoX2 范德华异质结光电探测器的制备方法和性能增强策略.最后,强调了这类异质结光电探测器当前面临的挑战及未来的发展方向.本综述将为这类高性能范德华异质结光电探测器的设计提供一定的指导和参考.
Abstract
Graphene is widely used in photodetection because of its high carrier mobility and wide spectral absorption range.However,its high dark current caused by its low light absorption severely limits its performance.Molybdenum dihalide(MoX2,X=S,Se and Te)has a high absorption coefficient,which can compensate for the high dark current in graphene-based photodetectors and result in outstanding photoelectronic properties of those based on a graphene/MoX2 van der Waals heterostructure(vdWH).In this review,we firstly review working principles,performance indicators,and structures of photodetectors.After that,the signific-ance of graphene/MoX2 vdWH photodetectors is highlighted from the fundamental perspective.Preparation methodologies and per-formance enhancement strategies of graphene/MoX2 vdWH photodetectors are correspondingly summarized.In the end,we high-light the current challenges and future directions of the graphene/MoX2 vdWH photodetectors.This review will guide the design of high-performance vdWH photodetectors.
