Using the tight-binding Hamiltonian and non-equilibrium Green’s function method, we have studied spin-dependent transport and controllable spin-flip effect in the presence of external Rashba spin–orbit interaction (RSOI) through armchair phosphorene nanoribbons (APNRs) with different widths. The results show that, by increasing the ribbon width, the spin-flip effect diminishes. Our probes suggest that creating splits in the effective positions in APNRs can improve the spin-flip effect which makes cleaved APNR structures a suitable candidate for designing improved spin inverters in future spintronic devices.
