Parametric resonance of acoustic and optical phonons in GaAs/GaAsAl quantum well in the presence of laser field
AbstractIn this paper, we analytically investigated the possibility of parametric resonance of acoustic and optical phonons. We obtained a general dispersion equation for parametric ampliﬁcation and transformation of phonons. The dispersions of the resonant acoustic phonon modes and the threshold amplitude of the ﬁeld for acoustic phonon parametric ampliﬁcation are obtained. The parametric ampliﬁcation for acoustic phonons in a GaAs/GaAsAl quantum well can occur under the condition that the amplitude of the external electromagnetic ﬁeld is higher than the threshold amplitude.
