摘要:
2D materials, such as exfoliated black phosphorous (or phosphorene), and layered metal dichalcogenides (LMDCs), in particular molybdenum disulfide (MoS2), possess sizable direct bandgap, and thereby have attracted much attention for their potential applications as electrocatalysts for logic circuits, optoelectronic devices, and “valleytronics”.
In this talk, I will summarize and discuss our recent work for interface engineered 2D materials (phosphorene and MoS2) based field-effect-transistors (FETs) and photo-transistors, through the combination of in-situ FET device evaluation and photoelectron spectroscopy investigation. We will particularly emphasize on the electron and hole doping effect on the transport properties and optoelectronic response of phosphorene devices.
