Starting with the discovery of two‐dimensional TIs, the HgTe‐based quantum wells [5, 6], many new topological materials have been theoretically predicted and experimentally observed. Currently known TI materials can possibly be classified into two families [7], the HgTe family and the Bi<jats:sub>2</jats:sub>Se<jats:sub>3</jats:sub> family. The signatures found in the electronic structure of a TI also cause these materials to be excellent thermoelectric materials [8–10]. On the other hand, excellent thermoelectric materials can be also topologically trivial. Here we present a short introduction to topological insulators and thermoelectrics, and give examples of compound classes where both good thermoelectric properties and topological insulators can be found.
