Scanning photocurrent microscopy reveals electron-hole asymmetry in ionic liquid-gated WS2 transistors
Nicolas Ubrig, Sanghyun Jo, Helmuth Berger +2
We perform scanning photocurrent microscopy on WS2 ionic liquid-gated field effect transistors exhibiting high-quality ambipolar transport. By properly biasing the gate electrode w…

Mono- and Bilayer WS2 Light-Emitting Transistors
Sanghyun Jo, Nicolas Ubrig, Helmuth Berger +2
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…
