摘要

Black phosphorus(BP), as a fast-emerging two-dimensional (2D) material, stands out from othermembers in 2D family such as graphene and transition metal dichalcogenides(TMDs), and attracts substantial research interests attributed to itsremarkably unique fundamental properties and versatile device applications. Inthis talk, I will summarize and discuss our recent work for interfaceengineered 2D materials phosphorene based field-effect-transistors (FETs) andphoto-transistors, through the combination of in-situ FET device evaluation andphotoelectron spectroscopy investigation. We will particularly emphasize on theelectron and hole doping effect on the transport properties and optoelectronicresponse of phosphorene devices.
