From: Band Structure of Topological Insulator BiSbTe1.25Se1.75
(a and c) show calculated bands of Se1 and Te terminated face of 6QL slab geometry of BiSbTeSe2 respectively. (b) Weight of atomic orbitals mainly contributing to the ‘V’ shaped band (enclosed in the black box) at the Γ point in Se terminated plain with respect to their distances from the surface. (d) Similar contribution to V shaped band at the Γ point (Ist) and slightly away from the Γ point (IInd) in Te terminated face.
