Brillouin light scattering has been used to study the elastic properties of an InSe film grown epitaxially on a hydrogen-terminated non-reconstructed Si(111) surface. Both generalized Rayleigh-Sezawa and Love acoustic modes have been revealed, and their velocity dispersions measured as functions of the ratio between the film thickness and the acoustic wavelength. This enabled us to determine the complete set of InSe film elastic constants through a non-linear best-fitting procedure.
