N-type PbTe compounds doped with Sb2Te3 have been prepared at high-pressure and high-temperature (HPHT). The thermoelectric properties of all the samples have been measured at room temperature. The Seebeck coefficients in absolute value and the electrical resistivities decrease with an increase of Sb2Te3 content dramatically first and then slowly. The thermal conductivity slight increases with an increase of the content of doping. The figure of merit, Z, increases first and then decreases and the maximum value reaches 8.7×10-4 K-1 which is much higher than that PbTe doped with PbI2 prepared at normal pressure. This result indicates that enhanced thermoelectric properties of PbTe can be obtained by the HPHT method with suitable dopant.
