It is generally assumed in the thermoelectric community that the lattice thermal conductivity of a given material is independent of its electronic properties. This perspective is however questionable since the electron–phonon coupling could have certain effects on both the carrier and phonon transport, which in turn will affect the thermoelectric properties. Using the SiGe compound as a prototypical example, we give an accurate prediction of the carrier relaxation time by considering scattering…
