Chalcogenide topological insulators

Abstract The purpose of this chapter is to introduce the reader to the chalcogenide materials systems that host the topological insulator phase of quantum matter. Specifically, the HgTe quantum well 2D topological insulator system and the V2VI3-type bismuth- and antimony-chalcogenide 3D topological insulator systems will be described. The chapter includes a general introduction to topological insulator systems, a description of the various growth methods for the synthesis of chalcogenide topological insulator materials, a review of notable studies and discoveries along with a description of several exotic topological states that have been shown to exist or are predicted to exist in these materials, and an outlook and summary.
