Recent Developments in One-Dimensional Inorganic Nanostructures for Photodetectors

摘要

With large surface-to-volume ratios and Debye length comparable to their small sizes, one-dimensional inorganic nanostructures have extensively been investigated and widely used to fabricate high-performance nano-scale electronic and optoelectronic devices. This feature article reviews the state-of-the-art research activities that focus on the one-dimensional inorganic nanostructures and their photodetector applications. It begins with a survey of one-dimensional inorganic nanostructures and the fundamentals of photodetectors. Some remarkable photoresponse characteristics are then presented, which are organized into sections covering several kinds of important nanostructures, such as ZnO, V_2O_5, ZnS, In_2Se_3, InSe, CdS, CdSe, ZnSe, Sb_2Se_3, ZrS_2, Ag_2S, and Zn_xCd_(1-x)Se. Each section describes the corresponding photodetective properties in detail. Finally, the article concludes with some perspectives and outlook on the future developments in the field.
