Abstract
Stacked InxGa1-xAs quantum dots (QDs) were grown by metal-organic chemical vapor deposition (MOCVD) via Stranski -Krastanov growth mode. AFM images show that the QDs structures were formed and the stacked structure of InxGa1-xAs QDs were confirmed by the HR-XRD analysis. Composition of the dots on the top most layers was related to the number of stack layers. The observed PL peak position was blue-shifted due to different number of stacked QDs. The PL intensity also dramatically increase, which shows the possibility of the QDs application in optical devices at room temperature
