Abstract : This paper presents a review of the novel features of the vibrational properties of the semiconductor superlattices, as studied mostly by Raman scattering. The concepts of folding and confinement applicable to acoustic and optic phonons and the existence of interface phonons are brought out. The role of Raman scattering in characterising the structural quality of the superlattices is mentioned.
