(a) Total (left panel) and spin (right panel) edge density of states for SnCN. In the spin edge plot, yellow/green lines denote the spin up/down polarization. The red dot line shows the Fermi level. (b) Real-space band decomposed charge density distribution from the edge states. The red/blue arrow denote the electrons with up/down spin.
