a Phase diagram as a function of magnetic field Bz and scattering range q0. The magnetic field Bz is applied perpendicular to the surface. The color map represents the ratio R between spin-up triplet and singlet pairing fields. Here, SC, TSC, and M denote trivial superconducting, topological superconducting, and metallic states, respectively. The red dashed curve represents the phase boundary between SC and TSC states. b The evolution of the singlet pairing field Δ↑↓ with the magnetic field Bz. c The evolution of the triplet pairing field Δ↑↑ with the magnetic field. Here, we set the Rashba spin-orbit coupling λSOC = 0.3t.
