Theoretical and experimental revision of surface acoustic waves on the (100) plane of silicon

Abstract The phase velocity dispersion of the surface acoustic waves on a basal plane of Si(100) has been calculated in the whole range of the azimuthal angle of propagation. We present a detailed description of the calculations. These calculations are compared with the experimental data obtained by...
