Summary on Grant Application Form |
|
This project will address the understanding and the demonstration of low-dimensional self-assembled quantum nanostructures obtained by organometallic chemical vapour deposition on patterned, nonplanar surfaces. The objective is to develop high quality, self-assembled quantum wire and quantum dot systems (single elements and arrays) with well-controlled positioning, dimensions, composition, and electronic spectrum. This will be achieved through the control of the surface chemical potential and hence the processes of transport and deposition of adatorns on a nonplanar surface via capillarity, strain and entropy of mixing effects. The experimental approach will include surface pattern preparation using nanolithography, monolayer-controlled epitaxial growth and structural studies using electron and scanning probe microscopy. Modelling of the self-assembly process will be implemented using advanced analytical models and numerical simulations. Optical spectroscopy will be used to evaluate the electronic structure of the obtained wires and dots, and the results will be compared with model simulations based on the structural measurements and modelling. The project is expected to yield better insight into seeded self-ordering phenomena and their application in useful nanosystems.
