摘要：

A Raman scattering experimental study of low-frequency acoustic phonons in one-dimensional periodic metallic Cu/Nb superlattices is presented. The approximation of elastic continuum and Thomas-Fermi are first used to interpret observed the phonon spectra of TA and LA modes in reduced Brillouin zone. One can find that the effective sound velocity in metallic superlattice is probably relevant to electron-phonon interaction.
