High Mobility Ambipolar MoS2 Field-Effect Transistors: Substrate and Dielectric Effects

Wenzhong Bao, Xinghan Cai, Dohun Kim +2

We fabricate MoS2 field effect transistors on both SiO2 and polymethyl methacrylate (PMMA) dielectrics and measure charge carrier mobility in a four-probe configuration. For multil…
