Abstract
The lattice distortion surrounding buried self-assembled InAs stressors can create strain-induced quantum dots (SIQD’s) in a nearby quantum well (QW). The optical properties of these new zero-dimensional systems are studied experimentally and compared to a simple theoretical model. We demonstrate that the photoluminescence energy of the SIQD’s can be tuned in a wide energy range by the QW width as well as by the spacing between the QW and InAs quantum dot layer.
