Chern number (a, b) and spin Chern number (c, d) with respect to intrinsic SOC strength λsoc for different staggered potential and Rashba SOC strength λR. In a, c, λR is fixed to be 0.05t. In b, d, λv is fixed to be 0.05t. Band structure of a finite system, with 40 unit cells in the y direction, for e λsoc = 0.02t and f λsoc = 0.05t. In both e, f, λR = 0.025t and λv = 0.05t. The edge states in the bulk band gap are colored blue or red depending on the spin polarization. a0 is the lattice constant. In all cases, λex = 0.1t.
