    Abstract

    The dispersion curves of confined acoustic phonons in ~10 and ~30 nm Si membranes were measured using Brillouin Light Scattering (BLS) spectroscopy. The dispersion relations of the confined phonons were calculated from a semi-analytical model based on continuum elasticity theory. Green’s function simulations were used to simulate the Brillouin spectra.
