In this Colloquium the theoretical foundation for topological insulators and 2010-12-08 Topological insulators have attracted much interest recently from Condensed Matter Physics as well as the wider scientific community. They are characterized by having bulk electronic states like that of a standard band gap insulator but with spin-momentum locked … Spin-based electronics in topological insulators (TIs) is favored by the long spin coherence1,2 and consequently fault-tolerant information storage. Magnetically doped TIs are ferromagnetic up to 13 K,3 well below any practical operating condition. Here we demonstrate that the long-range ferromagnetism at ambient temperature can be induced in Bi2–xMnxTe3 by the magnetic proximity effect 2020-03-19 2017-11-28 Our demonstration of room-temperature topological order and non-trivial spin-texture in stoichiometric Bi(2)Se(3).M(x) (M(x) indicates surface doping or gating control) paves the way for future graphene-like studies of topological insulators, and applications of the observed spin-polarized edge channels in spintronic and computing technologies possibly at room temperature. 9.

One such advancement is the topological insulator, a new phase of matter that stands on the boundary between insulation and conductance. This technology would allow for the eventual construction of the quantum computer, a revolutionary device that would use the dynamics of atomic-scale objects to store and manipulate information. Topological insulator (TI), a promising quantum and semiconductor material, has gapless surface state and narrow bulk band gap.

So far, magnetic topological insulators had only been created by the so-called extrinsic route, which consists of doping nonmagnetic topological the ordinary insulator from “weak” and “strong” topological insulators. These phases are characterized by the presence of gapless surface or edge states. In the two-dimensional quantum spin-Hall phase and the three-dimensional strong topological insulator, these states are robust and are insensitive to weak disorder and interactions. Thus, exploring the visible-range plasmonic response of topological insulators is significant to reveal their optical characteristics and broaden their applications at high frequencies. Herein, we report the experimental demonstration of a visible-range surface plasmon resonance (SPR) effect on an antimony telluride (Sb 2 Te 3 ) topological insulator film. These states have spin-momentum locked dispersion caused by time-reversal symmetry or mirror symmetry for topological insulators and topological crystalline insulators, respectively.
