Modifying the growth sequence during the capping of InAs islands, allows us to tune the thickness and lateral dimensions of the QDs while keeping the wetting layer thickness constant. Using the same method but embedding the tuned InAs islands into AlAs layers allows to further blueshift the photoluminescence emission to higher energies while keeping the wetting layer thickness constant. The main process responsible for the QDs size modification is consistent with a kinetically controlled materials redistribution of the InAs islands that minimizes the energy of the epitaxial layers at the start up of the GaAs capping deposition.The authors want to acknowledge the financial support of QUEST an NSF-Science and Technology center (DMR No. 91-20007), the Linköping University (POH), the Deutsche Forschungsgemeinschaft (PJW) and the Spanish Ministry of Education and Science (JMG) for financial support.Peer reviewedAmerican Institute of Physics201020101998info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/29024reponame:DIGITAL.CSIC.
