摘　　要：As an excellent optical device,photodetectors have many important applications,such as communication technology,display technology,scientific measurement,fire monitoring,aerospace and biomedical research,and ifs of great significance in the research of nanotechnology and optoelectronics.Graphene,as the first two-dimensional(2D)single-element nanomaterial,has the advantages of high carrier mobility,high strength,high light transmittance and excellent thermal conductivity,and ifs widely used in various nano-optical devices.The great success of graphene has led scientists to extensive research on other 2D single-element nanomaterials.Recently,a group of novel 2D single-element nanomaterials have attracted a lot of attention from scientists because of its excellent physical,chemical,electronic,mechanical and optical properties.Furthermore,it has opened a new door for the realization of new and efficient photodetectors.The group of 2D single-element nanomaterials are called 2D-Xenes and used to make high-performance photodetectors.Currently,there are few studies on photodetectors based on 2D-Xenes,but some 2D-Xenes have been applied to photodetectors and reported.Some of these have excellent photodetection performance,such as high photoresponsivity(R),broad spectral response range,fast photoresponse speed and high specific detectivity(D).Based on the novel 2D-Xenes,this review explores the types and preparation methods of 2D-Xenes,and the working mechanisms of 2D-Xenes photodetectors.Finally,the challenges and development trends of 2D-Xenes in the future are discussed.The research of 2D-Xenes is of great significance for the development of high-performance photodetectors in the future,and is expected to be widely used in other nanoelectronics and optical devices.
