Description

The authors present Raman scattering results on transverse acoustic phonons in metallic superlattice and have verified most expectations regarding acoustic phonon folding as in semiconductor superlattices. Raman folded peaks up to seventh order can be observed which agree closely with elastic continuum prediction in frequency. Owing to metal high optical absorption, phonon momentum nonconserving have caused increasing linewidth and disorder-activated transverse-acoustic mode scattering
