Mono- and Bilayer WS<sub>2</sub> Light-Emitting Transistors
Mono- and Bilayer WS<sub>2</sub> Light-Emitting Transistors
We have realized ambipolar ionic liquid gated field-effect transistors based on WS2 mono- and bilayers, and investigated their opto-electronic response. A thorough characterization of the transport properties demonstrates the high quality of these devices for both electron and hole accumulation, which enables the quantitative determination of the band gap (Δ1L …
