Selective resonant interaction between confined excitons and folded acoustic phonons in GaAs/AlAs multi-quantum wells
Résumé
We demonstrate strongly resonant selective interaction between confined excitons and folded acoustic phonons in multi-quantum wells and quantitatively reproduce each scattered spectrum based on the resonant interaction with a single periodized confined exciton. We emphasize the possible impact of these resonances on the generation and detection functions in picosecond acoustics on semiconductor multilayers. (C) 2013 AIP Publishing LLC.
