The small physical size of self assembled quantum dots gives rise to pronounced Coulomb interactions within the dots. By studying different excitons in the same quantum dot we show that the Coulomb interactions significantly alter the radiative recom

Dual‐laser excitation spectroscopy is performed on single quantum dots (QDs). Under excitation of a main laser with an energy above the wetting layer band gap, it is demonstrated that the QD luminescence is highly sensitive to exposure of infrared

We report the generation of neutral, negatively charged and positively charged excitons in the same single InAs quantum dot in a controlled manner. The control parameters of the respective excitons are a vertical electric field, applied to a capacito

We measured the second order correlation function between single photons emitted from optically excited single self‐assembled quantum dots embedded in planar microcavities. We clearly distinguish between radiative recombination processes in the pre
Visible luminescence has been obtained from ensembles of defect‐free, InxAl(1−x)As islands of ultrasmall dimensions embedded in AlyGa(1−y)As cladding layers. These structures were grown by molecular beam epitaxy and studied with low‐temperatu
