a, 2D color plot of dRxx/dB versus carrier density n and out-of-plane magnetic field B taken at D = 0.11 V/nm at a temperature of 100 mK. The dashed line indicates the C = -3 state. b, 2D color plot of dRxy/dn versus carrier density n and out-of-plane magnetic field B taken at D = 0.11 V/nm at a temperature of 100 mK. The dashed line indicates the C = -3 state. The C = -3 state is the only visible state on the hole doping side at low magnetic field and traces all the way to 0 T. On the electron side, a complete set of Landau levels is observed and disappears at around 1.5 T.
