Theory of electronic Brillouin scattering in metals
Falkovsky L.A., Mishchenko E.G.
The theory of the Brillouin light scattering in metals by conduction electrons interacting with acoustic phonons and impurities is developed. Effects of the surface and the Coulomb interaction of carriers are taken into consideration. The self-consistent electron-phonon interaction changes the electron-hole contribution -the wide relaxation continuum is appeared with the temperature dependent collision frequency.The sharp peaks in the cross section are arised due to exitation of the bulk longitudinal phonons, the bulk transverse phonons and the surface Ray lei gh phonons. The contribution of the bulk phonons re He Ó ted by the surface has the form of a narrow continuum with the sharp maximum for the slipping phonons.
