PLASMA THEORY OF ELECTRON-PHONON INTERACTION IN METALS
Technical Report
·
OSTI ID:4068602
The recently developed transport theory of an electron gas is extended to include interaction with ions in a metal. The perturbation of lattice vibrations induced by an anisotropy of the electron distribution is calculated. Subsequently the ionic degrees of freedom are eliminated from the transport equation of the electrons in favor of a long-range electron-correlation term. The influence of this term becomes important at long wavelengths (in the far infrared) but constitutes a small perturbation for the eigenfrequencies of collective motion of the electron gas. Nevertheless, the dispersion relation for the collective oscillations shows that the contributions from the phonon interaction are of the same order of magnitude as the influence of thermal agitation.
