Abstract

We report on temperature dependent photoluminescence measurements on single monolayer fluctuation GaAs/AlGaAs quantum dots. At low temperature, the exciton lineshape deviates from the expected Lorentzian profile, with the appearance of asymmetric acoustic phonon sidebands. The temperature dependence of the exciton lineshape and its asymmetry, are very well accounted by a model describing the non-perturbative coupling with acoustic phonons. The effect of confinement on these phonon sidebands is finally adressed.
