Recently, topological insulator materials have been theoretically predicted and experimentally observed in both 2D and 3D systems. We first review the basic models and …
Topological insulators display unique properties, such as the quantum spin Hall effect, because time-reversal symmetry allows charges and spins to propagate along the edge or …
Magnetic interaction with the gapless surface states in a topological insulator (TI) has been predicted to give rise to a few exotic quantum phenomena. However, the effective magnetic …

Thin films of V–VI compound semiconductors (Bi2Se3, Bi2Te3 and Sb2Te3) have been synthesized recently as three‐dimensional topological insulators (TIs). Although these …
We report a direct observation of surface dominated conduction in an intrinsic Bi2Se3 thin film with a thickness of six quintuple layers grown on lattice-matched CdS (0001) substrates …
We have investigated plasmonic excitations at the surface of Bi 2 Se 3 (0001) via high- resolution electron energy loss spectroscopy. For low parallel momentum transfer q∥, the …
The spin-orbit coupling field, an atomic magnetic field inside a Kramers' system, or discrete symmetries can create a topological torus in the Brillouin Zone and provide protected edge …
In topological insulators (TI) for surface electron transport, dissipationless surface states are required and are activated by symmetry breaking usually by reducing thickness of the film …

The electrical detection of the surface states of topological insulators is strongly impeded by the interference of bulk conduction, which commonly arises due to pronounced doping …
