Topological Insulators from a Chemist's Perspective

Heavy stuff: Topological insulators are formed of heavy atoms and host special surface or edge states. The electronic structure is characterized by a Dirac cone within a bulk band gap (see picture) that is generated by strong spin–orbit coupling. A chemist's perspective in terms of bonds, bands...

Summary:Heavy stuff: Topological insulators are formed of heavy atoms and host special surface or edge states. The electronic structure is characterized by a Dirac cone within a bulk band gap (see picture) that is generated by strong spin–orbit coupling. A chemist's perspective in terms of bonds, bands, symmetry, and nuclear charge is provided.
