Phonon replicas are investigated at the electric field induced r-X transition in GaAdAlAs coupled quantum well structures by photoluminescence spectroscopy. In the realand k-space indirect regime the observed replicas are assigned to AlAs LO, TO and LA zone-edge phonons. At the indirect-direct transition those phonons disappear and a new replica emerges… CONTINUE READING
