摘要
Two-dimensional materials,especially graphene-like emerging single-element materials two-dimensional(2D)Xenes,have attracted great research interest since the advent of the graphene.In this review paper,12 kinds of different Xenes were introduced according to the group and element quality,and their main synthesis methods are outlined.The advantages and limitations of the synthesis methods are analyzed in detail.By summarizing the current photoelectronic properties of 2D Xenes materials,it is found that Xenes in the same group have similar properties,such as the buckling properties of the fourth group and the anisotropy of the fifth group.In addition,the performance of photoelectronic applications based on 2D Xenes materials are summarized,and some possible methods are proposed to improve the perfor-mance of future 2D Xenes material photoelectronic devices.
