Optical characterisation of InAs quantum dots grown on {110} cleaved GaAs facets
We have grown InAs quantum dots on the {110} cleaved edges of (001) GaAs wafers. The lattice mismatch drives the formation of the quantum dots in a Stranski-Krastanow growth mode. We have investigated the properties of the resulting structures by atomic force microscopy, scanning electron microscopy, transmission electron microscopy and low-temperature cathodoluminescence. The growth of GaAs on th
