Topological insulators constitute a new state of condensed matter wherein the combined effects of time-reversal symmetry and spin-orbit coupling leads to invariants that are robust with respect to disorder. A generic consequence is the appearance of gapless modes at the interface between a topological insulator and conventional insulators (such as the vacuum). We are exploring the physical properties of narrow band gap semiconductors that are candidates for achieving a 3D topological insulator. The principal aim is to synthesize model 3D topological insulators whose behavior is modified by the vicinal coupling to symmetry-breaking order parameters such as superconductivity and magnetism.
