Coupled Bloch-phonon modes in superlattices

Ghosh, A. W.; Jönsson, L.; Wilkins, J. W.; Dekorsy, T.; Bartels, A.; Kurz, H.

Abstract

Experiments and microscopic theoretical analysis show that the coupling of Bloch
oscillations with coherent longitudinal optical phonons in a GaAs/AlGaAs
superlattice leads to resonant coherent phonon excitation but no gap in the Bloch-phonon spectrum.
