Abstract

It is found that the phonon flux generated by an external source induces a change of the luminescence bandshape of an ultrathin quantum well CdTe/ZnTe excited quasi-resonantly by a He-Ne laser. The effect of nonequilibrium phonons manifests even at small lasing power and large distance between the phonon generation zone and the quasi-resonant luminescence excitation zone. It is assumed that the phonon flux induces the tunnel transitions between localized exciton states; these transitions are accompanied by stimulated phonon emission. This paper was presented at the 3rd Russian Workshop on Nanophotonics, Nizhnii Novgorod, Russia, 26-29 March 2001.
