Abstract

We studied quantum dot arrays using m-PL measurements. Clear multi-excitonic spectra are observed, which are attributed to homogeneous ensembles of QDs in the array. The spectra can be explained by applying a Hartree-Fock based model including the twobody Coulomb and exchange interactions. Eight lines in the m-PL spectrum are attributed to bi-exciton, excited bi-exciton and multi-exciton transitions. These lines show a clear nonlinear behavior since they only appear at high excitation power.
