About Bismuth Telluride

Bismuth telluride is the working material for most Peltier cooling devices and thermoelectric generators. This is because Bi2Te3 (or more precisely its alloys with Sb2Te3 for p‐type and Bi2Se3 for n‐type material) has the highest thermoelectric figure of merit, ZT, of any material around room temperature.

Bismuth telluride based thermoelectric semiconductors are high performance thermoelectric materials over the low to medium temperature range (~300 degree ), which have found important applications in local thermoelectric cooling and precise temperature control in the fields of micro-electronics, computer and aerospace, and have prospect in industrial waste heat recovery for thermoelectric generation. Alloying and doping are effective ways to improve thermoelectric properties of bismuth telluride by enhancing the phonon scattering to reduce the lattice thermal conductivity, and optimizing the carrier concentration to increase power factor.

we reviewed the enhancement of thermoelectric properties of bismuth telluride by alloying and doping, the growth of the bismuth telluride crystals as well as the effect of space microgravity on the growth of bismuth telluride crystals by zone melting process.
