Abstract:
The effect of nonequilibrium acoustic phonon flux on the photoluminescence of an ultrathin quantum well CdTe/ZnTe upon its quasi-resonant excitation by a He-Ne laser was studied. It is found that the phonon flux generated by an external source affects the quantum well luminescence bandshape even at small lasing power and large (up to $1$ cm) distance between the phonon generation zone and the quasi-resonant luminescence excitation zone. It is assumed that the phonon flux stimulates exciton in-plane (lateral) migration in the quantum well through the tunneling between the local potential minima accompanied by induced phonon emission.
