Inelastic light scattering at metal-insulator transition: ripple and elasto-optic mechanisms
Falkovsky L. A. , Mishchenko E. G.
The inelastic light scattering in metals and insulators by acoustic and optical phonons is considered. The ripple and elasto-optic mechanism are taken into account. The phonon damping and skin effect are analyzed. The surface contribution to the cross section is found to be insensitive to the skin depth. The influence of the carriers on the bulk contribution through the skin effect and through the phonon damping is essential. The recent experimental data for fullerides are discussed. © 1995 American Institute of Physics.
