Extended Data Fig. 8: Chern insulators at the negative side of D.

a, 2D color plots of Rxx (upper panel) and Rxy (lower panel) at B = 1 T, revealing three Chern insulator states at the hole-doped side in the gap-closing range of D. The state with a Chern number C = -5 happens at D = -0.15 V/nm, while two states with C = -3 happen at D = -0.093 V/nm and D = -0.2 V/nm, as indicated by the dashed lines. b, c, d, 2D color plots of Rxx (upper panel) and Rxy (lower panel) versus n and B at D = -0.15 V/nm, -0.093 V/nm and -0.2 V/nm respectively. The dashed lines indicate the n-B relation of the Chern insulators as predicted by the Streda formula. These results are consistent with those of the positive D side.
