Robust behavior and spin-texture stability of the topological surface state in Bi2Se3 upon deposition of gold
Abstract The Dirac point of a topological surface state (TSS) is protected against gapping by time-reversal symmetry. Conventional wisdom stipulates, therefore, that only through magnetisation may a TSS become gapped. However, non-magnetic gaps have now been demonstrated in Bi2Se3 systems doped with...
