Optical and morphological properties of In(Ga)As/GaAs quantum dots grown on novel index surfaces
Optical and morphological properties of self assembled In(Ga)As/GaAs quantum dot systems, grown on high index (N11) substrates, for a wide range of orientations, coverages and compositions, are presented and reviewed. The use of high Miller index substrate orientations permits to intervene on major quantum dots properties such as shape, size distribution, transition energy and emission polarisation, thus opening a wide range of device design opportunities.
