摘　　要：Two-dimensional materials have shown great application potential in high-performance electronic devices because they are ultrathin,have an ultra-large specific surface area,high carrier mobility,efficient channel current regulation,and extraordinary integration.In addition to graphene,other types of 2D nanomaterials have also been studied and applied in photodetectors,solar cells,energy storage devices,and so on.Bi_(2)O_(2)Se is an emerging 2D semiconductor material with very high electron mobility,modest bandgap,near-ideal subthreshold swing,and excellent thermal and chemical stability.Even in a monolayer structure,Bi_(2)O_(2)Se has still exhibited efficient light absorption.In this mini review,the latest main research progresses on the preparation methods,electric structure,and the optical,mechanical,and thermoelectric properties of Bi_(2)O_(2)Se are summarized.The wide rang of applications in electronics and photoelectronic devices are then reviewed.This review concludes with a discussion of the existing open questions/challenges and future prospects for Bi_(2)O_(2)Se.
