Photostimulated attenuation of hypersound in superlattices

Superlattices and Microstructures, Volume 22, No. 4, Year 1997

Photostimulated attenuation of hypersound in semiconductor superlattices has been investigated theoretically. It is shown that the attenuation coefficient depends on the phonon wave vector q in an oscillatory manner and that from this oscillation the band width Δ of the superlattice can be found. © 1997 Academic Press Limited.
