Abstract
The capping of an array of self-assembled InAs/GaAs quantum dots by an InGaAs quantum-well layer leads to an increase in their size due to indium enrichment of the region near the top of the quantum dots, which decreases the energy of the ground-state optical transition in quantum dots by 50 meV and shifts the hole wave function toward the top of the quantum dot.
