      Interplay of Topological States on TI/TCI Interfaces 

      Menshchikova, Tatiana V.; Eremeev, Sergey V.; Kuznetsov, Vladimir M.; Chulkov, Evgueni V. (MDPI, 2020-10-10)
      Based on first-principles calculations, we study electronic structure of interfaces between a Z2 topological insulator (TI) SnBi2Te4 and a topological crystalline insulator (TCI) SnTe. We consider two interface models ...
