In integrating topological insulators (TIs) with conventional materials, one crucial issue is how the topological surface states (TSS) will behave in such heterostructures. We use first-principles approaches to establish accurate tunability of the vertical location of the TSS via intriguing dual-proximity effects. By depositing a conventional insulator (CI) overlayer onto a TI substrate (Bi₂Se or Bi₂Te₃), we demonstrate that, the TSS can float to the top of the CI film, or stay put at the CI/TI ...[more]
