Abstract

Topological insulators are nonmagnetic insulators in the bulk, but have gapless edge/surface states characterized by Z2 topological numbers. In this paper we review basic properties of topological insulators. We then focus on the two-dimensional topological insulators, and describe various properties of the edge states.
