Figure 8From: Tunable insulator-quantum Hall transition in a weakly interacting two-dimensional electron systemR H and ln( Δρ xx ( B , T )/ D ( B , T )). (a) RH as a function of T for both gate voltages. ln(Δρxx(B, T)/D(B, T)) as a function of 1/B is shown in (b) and (c) for Vg = −0.05 and −0.1 V, respectively. The dotted lines are the fits to Equation 1.Back to article page
