Breakdown of Herring's processes in cubic semiconductors for sub-terahertz longitudinal acoustic phonons

In the present work we explain the anomalous behavior of the attenuation of the longitudinal acoustic phonon in GaAs as a function of the phonon energy ω in the sub-THz domain. These attenuations along the [100] direction show a plateau between 0.6 and 1 GHz at low temperatures. We found an excellen...
