Abstract
We have calculated the effect of phonon drag on the electrical resistivity and the thermopower of the alkali metals. The calculations are an extension of our previous work on select transport properties of the alkalis. For the electron–ion interaction we use the pseudopotentials that we developed from resistivity data. Realistic phonons obtained from inelastic neutron scattering results on the dispersion curves are employed. This means that no adjustable parameters enter our calculations. Good qualitative agreement with experiment is obtained for the phonon drag thermopower.Keywords
