Superlattice umklapp processes in resonant Raman scattering
Abstract
Umklapp resonant Raman scattering by LO phonons is observed in GaAsGa1-xAlxAs superlattices as a result of minizone formation in the conduction and valence bands. The scattering mechanism involves the wavevector dependent Fröhlich-type electron-phonon interaction. © 1978.
