Surface Brillouin scattering is used to determine the velocities of the Rayleigh surface wave, pseudo-surface wave and longitudinal lateral wave measured in the [100] and [110] directions in a (100) surface of single crystal InAs0.91Sb0.09. Explicit secular functions for the wave velocities are used to extract the elastic constants.
