From: Substitution-induced spin-splitted surface states in topological insulator (Bi1−xSbx)2Te3
The calculated electronic structures of (Bi1−xSbx)2Te3.
(a), (b) Projected band structures of surface layer and bulk layer of pure Bi2Te3, respectively. (c), (d) Projected band structures of surface layer and bulk layer of BiSbTe3, respectively. (e) Total bands of BiSbTe3 surface layer and the decomposed bands projected on (f) Bi, (g) Sb and (h) Te atoms. The size of red balls corresponds to band weight and small-size balls with tiny contributions are omitted. In other words, the size of balls indicates the intensity of states.
