The n-type thermoelectric materials of PbTe alloyed with PbSe (PbTe1-xSex) were prepared by high-pressure and high-temperature method. The structure and electrical properties of PbTe1-xSex were studied at room temperature. X-ray diffraction results indicated that the PbTe1-xSex sample exhibited the NaCl crystal structure. As the increasing of Se content x, the lattice parameter, Seebeck coefficient and resistivity for PbTe1-xSex all decrease, and the power factor increases first and then decreases. The maximum power factor of 21.7 μW/(cm·K2) was obtained at the x=0.1, which is about 20% higher than that of PbTe.
