Interface-dominated topological transport in thermoelectric Bi2Te3
Hörsaal 2 Bismuth telluride, Bi 2 Te 3 , is an excellent thermoelectric material and also belongs to the class of three-dimensional topological insulators (3D TIs). In 3D TIs, the availability of protected [...] Going back to the motivation of Bi 2 Te 3 as a traditional thermoelectric material, this means that good thermoelectric properties of nanoparticulate Bi 2 Te 3 near room temperature are also determined [...] contribute charge carriers with extremely high mobility. But usually, transport measurements in Bi 2 Te 3 bulk samples do not show any signatures of high-mobility charge carriers. In nanoparticulate samples …
