Tetradymite-type materials, such as Bi2Te3, have for decades been of interest as excellent thermoelectrics near ambient temperature and have recently enabled many seminal studies on topological insulators. In this Review, we discuss the recent progress in optimizing the properties of bulk and thin-film tetradymites for such studies.
