(color online) (a) Gate dependence of the resistivity at different temperatures for Run7. Temperature is labeled using different colors. Inset: Gate dependence of the resistivity of pristine graphene at T = 7.1 K and T = 300 K. (b) Temperature dependence of the resistivity at Dirac point for Run7. Inset: ρDirac versus 1/T in a semi-log plot. The solid line is the thermal activation model fitting as described in the main text.
