InAs/GaAs quantum dots (QDs) on GeOI were grown at various growth temperatures and in-depth photoluminescence study was conducted to characterize the optical properties of QDs on GeOI. InAs QDs with room temperature emission of 1.26 μm and areal density of 4.8 × 1010 cm-2 were obtained. It was shown...
