摘要：

High concentration of Er3+/Yb3+ co‐doped WS2 monolayer is creatively prepared by in‐situ chemical vapor deposition technique. The performances of the devices (photodetectors and field‐effect transistors) are significantly enhanced after rare‐earth (RE) co‐doping, which can be attributed to the stronger light absorption and higher the transitions of electronic states, providing an excellent strategy for practical application in optoelectronics. Abstract Chemical doping is a significant means to modulate bandgap structures and optoelectronic...
