(a) Rvert/R0 as a function of Vbg. While the thickness of MoS2 is 50 nm for Gr/MoS2/(Cr/Au) VEFT, the thickness of MoS2 is 48 nm for (Cr/Au)/MoS2/(Cr/Au) VEFT. (b) Rplanar/R0 as a function of Vbg for 48 nm-thick MoS2 in planar geometry. Reference resistances (R0) were taken at Vbg = −10 V. All measurements were done at T = 300 K.
