The calculated semi-infinite edge states of total (a) and spin (b) for InBiCH3. The red and green components in (b) denote the spin up and spin down polarization. The Fermi level is set to zero. (c) Evolutions of Wannier centers along ky. The evolution lines cross the arbitrary reference line (red dash line) parallel to ky odd times, yielding Z2 = 1.
