  • Consistent with the state of art thermoelectric material PbTe, PbSe belongs to group Ⅳ-Ⅵ semiconductor. And PbSe has the same crystal structure as PbTe. But there are few reports about PbSe as thermoelectric material. A large number of studies show that the thermoelectric performance of PbTe is improved effectively under high pressure. In this paper, PbSe was synthesized by high pressure and high temperature method. The phase compositions and microstructures of PbSe were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The electrical properties measurement results show that PbSe sample synthesized under high pressure has low electrical resistivity and high power factor, and therefore it is a promising thermoelectric material applicable to thermoelectric power generation.
