N2 - In an attempt to reduce our reliance on fossil fuels, associated with severe environmental effects, the current research is focused on the enhancement of the direct thermal to electrical thermoelectric efficiency of n-type PbTe by Na and Cl co-doping. We show that such co-doping is expected to enhance the thermoelectric efficiency by more than 17% compared to any of the previously reported lanthanum or iodine doped single-phase compositions, due to reduced lattice thermal conductivity values, originated by lattice disordering and mass/radii fluctuations in addition to improved carrier mobilities, originated by lower effective masses.
