The thermopower of PbTe as a function of temperature and doping level is reported based on Boltzmann transport calculations using the first principles relativistic electronic structure as obtained with the Engel-Vosko generalized gradient approximation. The results are discussed in relation to experimental data. For p-type material there is an enhancement at high-doping levels due to the onset of an increased density of states starting {approx}0.2 eV below the valence band edge. This leads to agreement between the calculated thermopower and recent results on PbTe with heavy Tl doping.
