a Schematic of experimental setup. b–dI–V measurements of CVD grown MoS2, ReS2, and graphene monolayer with small (A < 50 nm2) W probes, respectively. The inset show TEM images of the contact morphology and scale bars = 0.5 µm. The measured contact area (A), fitting model and the fitting parameters are also shown. The solid lines indicate the fitted range. e–gI–V measurements of CVD grown MoS2, ReS2, and graphene monolayer with large (A > 95 nm2) W probes, with inset TEM images of the contact morphology, scale bars = 0.5 µm. The complete fitting curves can be seen in Supplementary Fig. 2.
