title: In situ measurement of electrical resistivity and Seebeck coefficient simultaneously at high temperature and high pressure.
abstract: A method for performing simultaneous measurements of the electrical resistivity and the Seebeck coefficient at high pressure and high temperature (HPHT) in cubic multi-anvil apparatus is described. For high pressure and high temperature measurements, a four-probe arrangement is used to measure the electrical resistivity and two pairs of chromel-alumel type thermocouples are employed to determine the Seebeck coefficient, respectively. Results of an expected temperature-induced phase transition, pressure-induced metallization and enhancement of the thermoelectric properties were obtained in Ag2Te. This method can provide the necessary data of thermoelectric materials at HPHT.
