During the 1970’s, more than 100 papers have been published in the field. However, most of them merely use some parametrized ion interaction which i

We present calculations of surface acoustic phonons in the long wavelength limit for a semi-infinite medium in order to explain the Brillouin cross section. The cases of GaAs and of A1 coated Si are considered. The surface optical phonons that are rapidl
