石墨烯/钼基二硫族化合物范德华异质结光电探测器的研究进展
Advances in graphene/molybdenum dichalcogenide-based van der Waals heterostructure photodetectors
摘要
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.关键词
