Thermoelectric properties and phase transitions in Bi2Te3 under hydrostatic pressure up to 9 GPa and temperature up to 300 °C

The thermoelectric tensor component S11 and the relative electrical resistance along the binary axis of Bi2Te3 single crystals of p- and n-type are measured under hydrostatic pressure up to 9 GaP and temperatures from 20 to 300 °C. A P-T phase diagram of bismuth telluride is proposed, which is different from diagram, obtained under nonhydrostatic conditions.
