Abstract

Topological insulator (TI) crystals are bulk insulators with robust conducting surface states protected by time-reversal symmetry due to strong spin-orbit coupling (SOC). These TI materials have been widely investigated for spintronic applications and quantum computation [1], and now are considered emerging optical materials for surface plasmonics [2]. Among these TI materials, Bi2-xSbxTe3-ySey (BSTS) shows superior properties of large bulk resistance and surface-dominated transport, as well as negative permittivity and low-loss plasmonic resonances in the visible part of the spectrum [3].
