Abstract

We report on Coulomb correlation effects in the luminescence of strain‐induced quantum dots. In single dots, under low power excitation, we observe the rising of sharp lines associated to the formation of excitonic molecules. In the grand‐ensemble, in magnetic fields up to 45 T, we observe Darwin‐Fock states of the dots to merge into a unique Landau level, with a considerable reduction in the total diamagnetic shift due to the enhanced electron–hole correlation caused by the increased degeneracy of the state.
