Spatial confinement of self-organized MBE-grown InxGa1?xAs quantum dots
Several samples with InxGa1?xAs quantum dots have been grown by molecular beam epitaxy using the self-organization method. The substrate temperature was varied from sample to sample and atomic-force-microscopy measurements were carried out to investigate the influence of this parameter on the morphological characteristics of the dots. We observed that, under certain conditions related to the initial cleaning process, the nanostructures could be confined within some regions of the sample.
