Development of experimental and theoretical tools for the determination of confinement and exciton levels in single layers of quantum dots

Nature of the result:
The result involves the development of a methodology for the determination of the confinement and excitonic properties of self-assembled quantum dots (QDs) and other self-assembled semiconductor nanostructures. These issues are at the core of the physics of self-assembled nanostructured materials, and are therefore of crucial importance not only for our fundamental understanding of their properties, but also for their exploitation as (opto)electronic devices.

Potential applications of the result:
The result can be applied to understanding the electronic and optoelectronic properties of all semiconductor nanostructures, and therefore has a very general applicability.

End-users of the result:
The end users of this result are all those involved in the research and development of semiconductor nanostructure (devices). This includes members of the project
consortium, the wider scientific community and industry.

Main innovative features/benefits:
The result offers the possibility for an advanced understanding of the properties of self-assembled semiconductor nanostructures, offering substantially improved insight over the previous state of the art. This will benefit further research and improve the knowledge/design of semiconductor nanostructure based devices.

Analysis of market or application sectors:
The result is a principally scientific one, so such an analysis is not applicable.

Potential barriers:
Full use of the result requires specialist knowledge and/or infrastructure, however a more general understanding of the broad features of the result should still have wide applicability.
