Abstract

Topological insulators are novel materials that belong to the broader class of quantum matter. In the bulk, a topological insulator behaves like an ordinary insulator with a band gap. At the surface, gapless states exist, which have a spin-helical Dirac dispersion. This peculiar spin structure renders topological insulators promising materials for spintronic applications. We review the underlying symmetry and topology concepts with the outlook that they determine the electronic, spintronic and optoelectronic properties of topological insulators.
