Quantitative Determination of the Band-Gap of WS2 with Ambipolar Ionic Liquid-Gated Transistors

Daniele Braga, Ignacio Gutiérrez Lezama, Helmuth Berger +1

We realized ambipolar Field-Effect Transistors by coupling exfoliated thin flakes of tungsten disulphide (WS2) with an ionic liquid-dielectric. The devices show ideal electrical ch…
