Аннотация

Exciton-plasmon interaction was studied experimentally in structures with InAs/AlGaAs quantum dots (QDs) and indium nanoclusters grown by molecular beam epitaxy. In photoluminescence (PL) spectra, a strong enhancement of low energy QDs was observed that resulted in a new peak. This effect is explained with the plasmon-assisted energy transfer from an ensemble of donor QDs located under a metal cluster to a low energy acceptor QD. The dependence of the integrated PL signal of the low new peak on the QD number under an individual metal cluster changed from linear to quadratic and revealed the transition from a single to many interacting QDs.
