(color online) (a) Log–log plot of gate dependence of the resistivity as a function of |Vg − Vmin| for the pristine sample. (b)-(f) Log–log plot of gate dependence of the added resistivity as a function of Vg − Vmin for Run2– Run6. The blue and red dots represent electrons and holes respectively. The solid line indicates the fitting to |Vg − Vmin|δ. |
