Abstract
The high-frequency acoustic-phonon scattering by electrons in superlattices in the presence of an intense radiation field is discussed. It is shown that in the intense field regime of the electromagnetic wave the hypersound attenuation coefficient may revert its sign and hypersound amplification can be obtained. An application is made for GaAs based superlattices.
