摘要：

Thermoelectric materials PbSe were successfully prepared by high pressure and high temperature technique (HPHT) and the pressure-dependent thermoelectric properties were studied from 300 to 600 K. The measurement results indicate that the electrical conduction type in PbSe can be changed from p- (< 2.0 GPa) to n-type (> 2.0 GPa) by application of pressure of about 2.0 GPa. And the electrical resistivity can be reduced effectively by pressure. Low thermal conductivity (similar to 0.8 W/mK) is obtained for high pressure synthesized PbSe. These results indicate that high pressure provides a viable and controllable way of tuning the thermoelectric properties for PbSe. Crown Copyright (C) 2014 Published by Elsevier Ltd.
