Band structures of ZnTe/Bi₂Se₃ and ZnTe/Bi₂Se₃ along the K–Γ–M direction.

Band structures of the relaxed ZnTe/Bi₂Se₃ system (top row), the ZnTe/Bi₂Se₃ system with an increased separation of 3 Å from 2.5 Å between the 1^st QL and 2^nd QL of the TI substrate (second row), the ZnTe/Bi₂Se₃ system with an increased separation of 3 Å from 2.6 Å between the CI and 1^st QL (third row) and the relaxed ZnTe/Bi₂Se₃ system (bottom row). All other symbols are the same as in Fig. 2.
