a, \({R}_{{\rm{xy}}}\) (top) and \({R}_{{\rm{xx}}}\) (bottom) of Device 2 as a function of top and bottom gate voltages at B = 11.8 T and T = 10 \({\rm{m}}\)K (lattice temperature). The Landau levels (identified by the resistance minimum) are indexed. b, c, \({R}_{{\rm{xy}}}\) (top) and \({R}_{{\rm{xx}}}\) (bottom) as a function of filling factor and magnetic field at E = 0.435 V/nm (before band inversion, b) and at E = 0.463 V/nm (near band inversion, c). The dashed lines show the Landau fan. The white oval shows the Landau level that disperses with a negative slope.
