The first models of 3D topological insulators were proposed by B. A. Volkov and O. A. Pankratov in 1985, and subsequently by Pankratov, S. V. Pakhomov, and Volkov in … 展开

Spin-momentum locking in the topological insulator allows symmetry-protected surface states to host Majorana particles if superconductivity is … 展开

Topological insulators can be grown using different methods such as metal-organic chemical vapor deposition (MOCVD),
physical vapor deposition (PVD), … 展开

Bloch's theorem allows a full characterization of the wave propagation properties of a material by assigning a matrix to each wave vector in the Brillouin zone.
Mathematically, this assignment creates a vector bundle 展开

2D Topological insulators were first realized in system containing HgTe quantum wells sandwiched between cadmium telluride in … 展开

The physical vapor deposition (PVD) technique does not suffer from the disadvantages of the exfoliation method and, at the same time, it is … 展开

The first step of topological insulators identification takes place right after synthesis, meaning without breaking the vacuum and moving the sample to an atmosphere. That could be done by using angle-resolved photoemission spectroscopy (ARPES) … 展开
