Abstract
We present calculations of the Brillouin cross section for a metallic thin film (Al and Au) on a Si substrate. The results for the Al coating are explained in terms of scattering from the surface corrugation due to the thermally excited acoustic phonons. In the case of Au we find an appreciable contribution from the elasto-optic coupling in the film.
