Effect of normal phonon-phonon scattering on the mutual electron-phonon drag and kinetic phenomena in degenerate conductors

The effect of normal phonon-phonon scattering processes on momentum relaxation in a nonequilibrium electron-phonon system is considered. A system of rate equations for the electron and phonon distribution functions has been solved with the inclusion of mutual electron-phonon drag. The kinetic coefficients of conductors have been calculated in a linear approximation in the degeneracy parameter. The effect of normal phonon-phonon scattering processes on the electron-phonon drag and on the kinetic phenomena in conductors with degenerate carrier statistics is analyzed.
