Crystal insulator
WebA quantum spin Hall insulator (QSH), or a two-dimensional topological insulator, possesses an insulating bulk, and topologically protected dissipationless edge states that bridge the energy gap opened by band inversion and strong spin-orbit coupling. WebInsulators and semiconductors have large cohesive energies; these solids are bound together strongly and have good mechanical strength. Metals with electrons in sp -bonds have very small cohesive energies. This type …

Web1.2 Introduction to 3D topological insulators. A 3D TI is characterized by an insulating bulk band gap and gapless conducting topological surface states (TSS) of spin-helical massless 2D Dirac fermions. The conducting edge in a 3D TI is a closed 2D surface (while in a 2D TI it is a 1D edge channel). Simple versions of 3D TI materials have been ...
