Abstract

Topological insulators are predicted to present interesting surface transport phenomena but their experimental studies have been hindered by a metallic bulk conduction that overwhelms the surface transport. We show that the topological insulator ${\text{Bi}}_{2}{\text{Te}}_{2}\text{Se}$ presents a h...
