Free induction decay processes of coherent folded longitudinal acoustic phonons in GaAs/AlAs finite size superlattices: control through the design of phonon dispersion curves
We present the concept on coherence that, in finite-size systems, free induction decay time is controllable through appropriately designing frequency dispersion curves as function of wave vector. We confirmed the present concept from numerical calculation of free induction decay time of coherent fol...
