a Band structure corresponding to SnTe. b Band structure of the 40-layer slab in the (001) direction. c The decay of superconducting pairing with the number of layers. d Energy of the BdG Hamiltonian of the system at surface Dirac cone as a function of the surface spin splitting Mz, This can be viewed as a topological phase diagram. e, f BdG spectrum, and the Wilson loop with Mz = 0.08 eV, the corresponding Chern number is −4. g partial enlargement of f to see that the Chern number of the system at this point is −4.
