Figure 6

Current–voltage characteristics of three PMLG samples at various temperatures. (a) Sample with number of graphene layers N = 18, (b) N = 14, (c) N = 11, and (d) differential conductance at zero bias as a function of T1/2 of three PMLG samples of N = 18, N = 14, and N = 11 graphene layers. The red dashed curves are the fit lines of the data and show good agreement with the Efros-Shklovskii variable-range-hopping model over the considered temperature range.
