Bismuth telluride (Bi2Te3)ke thepa ea thermoelectric e tsejoang ka bokhoni ba eona ba ho fetola matla a futhumatsang hore e be matla a motlakase. Haholo-holo e entsoe ka mefuta e 'meli: P-mofutaBi0.5Sb1.5Te3le N-mofuta oa Bi2Te2.7Se0.3. P-type Bi0.5Sb1.5Te3 haholo-holo e entsoe ka bismuth, antimony le tellurium, ha N-type Bi2Te2.7Se0.3 e na le bismuth, tellurium le selenium. Mefuta ka bobeli ea bismuth telluride e fumaneha ka foromo ea letlapa kapa phofo.
Likopo tsabismuth tellurideP-mofuta oa Bi0.5Sb1.5Te3 le N-mofuta oa Bi2Te2.7Se0.3 li haholo-holo tšimong ea phetoho ea matla a thermoelectric.
