Role of surface termination in realizing well-isolated topological surface states within the bulk band gap in TlBiSe${}_2$ and TlBiTe${}_2$

Bahadur Singh, Hsin Lin, R. Prasad +1

Electronic structures associated with the flat (polar) Se/Te- or Tl-terminated surfaces of TlBiSe${}_2$ and TlBiTe${}_2$ are predicted to harbor not only Dirac cone states, but also tr…
