a, High-resolution 2D plot of R. Correlated insulating features emerge in the second moiré band. b, Line plots extracted from the dashed lines in a for selected displacement fields. The dashed arrows indicate peaks at n = 7n0 and \(7\frac{2}{3}{n}_{0}\). c,d, Differential resistance versus d.c. bias current at various displacement fields and temperatures, respectively. e, Resistance in log scale versus \({T}^{-\frac{1}{2}}\) at selected \({B}_{\parallel }\). Inset, resistance in log scale as a function of \({T}^{-0.7}\) at large \({B}_{\parallel }\). f,g, 2D map of R as a function of the filling factor and parallel (perpendicular) magnetic field measured at D = −0.46 V nm−1.
