Topological insulator FET is also the critical device architecture for further optoelectronics and spintronics applications.

The introduction of topological protection of light has revolutionized the traditional perspective of wave propagation through the demonstration of backscatter-free waveguides in the presence of sharp bending and strong structural defects. The topological invariants of an interacting insulator can be calculated from Green’s function at zero-frequency. Nonzero frequencies can be safely ignored. (Wang&Zhang PRX, 2, 031008) This is a general framework instead of a single formula. It is applicable to many different topological insulators and superconductors.

Topological insulator applications

11 Feb 2020 The SOT generator layer may include topological insulator material, and the magnetic memory layer may Application Number: 15/497,591. 19 Nov 2018 On the other hand, the topological insulators are expected to have a wide range of applications to spintronics. In order to generate a topological insulator state, however, strong spin-orbit interaction is indispensabl and phases, which has possible applications to quantum computing. A primer on topological insulators.

The topological properties (especially the quantum spin Hall effect and Dirac fermion feature) and potential applications have been summarized. This review also

Instead, it concerns the wavefunctions of the electrons flowing in the material. These contain what is in effect a knot, making it impossible to smoothly convert a topological insulator into a normal insulator. Whereas electrons usually have a mass, in the case of topological insulators the conducting electrons on the surface have no mass and are automatically "spin polarized," leading to the unique half-integer quantum Hall effect observed and also making the material promising for various potential applications.

face states of a 3D topological insulator do strongly resemble the edge states of a 2D topological insulator. As in the 2D case, the direction of electron motion along the surface of a 3D topological insulator is deter-mined by the spin direction, which now varies continu-ously as a function of propagation direction (figure 1d).

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.
