Superconductivity in Topological Insulator Sb2Te3 Induced by

The two-dimensional (2D) topological insulator is a quantum spin Hall insulator, which is a close cousin of the integer quantum Topological insulators are insulating in the bulk, but process metallic states around its boundary owing to the topological origin of the band structure. The metallic edge or surface states are immune to weak disorder or impurities, and robust against the deformation of the system geometry.

Particularly, most of the Topological Insulators - Notebooks for an introductory course. This repository contains jupyter notebooks used in the introductory course given at the Eötvös University on topological insulatros. The course is accompanied by a set of lecture notes as well. We predict an unexpected and nontrivial quantum phase termed "topological Anderson insulator," which is obtained by introducing impurities in a two-dimensional metal; here disorder not only causes metal-insulator transition, as anticipated, but is fundamentally responsible for creating extended edge states.

Its 3D analogue, a weak topological insulator (WTI), possesses similar quasi-1D topological states confined at side A topological insulator is a material that behaves as an insulator in its interior but whose surface contains conducting states, meaning that electrons can only move along the surface of the material. Se hela listan på scholarpedia.org Topological insulators form a class of insulators distinct from all other insulating materials. These materials are distinguished from ordinary insulators by an inverted bulk gap for electronic excitations induced by strong spin-orbit coupling which assures the presence of gapless metallic boundary states, akin to the chiral edge modes in quantum Hall systems, but with helical spin textures [1–3] .

The bulk of such materials is insulating but the surface can conduct electric current with well-defined spin texture. The award recognized their theories that predicted the existence of topological insulators, a new class of material with the unique property of being an electrical insulator on the inside and having a surface that conducts electricity. There are few mistakes in the equations and the physical explanations behind topological insulators are forgotten throughout a vast quantity of equations - however, this may be a reflex of some difficulty of the author to express himself in English. The lack of examples is another major shortcoming from a pedagogical point of view. Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have protected conducted states on their edge or surface.
