Determination of the onset and mechanism (i.e. via electrons not holes) of electronic coupling between stacked InAs/GaAs quantum dots

Nature of the result:
The most fundamental issue for stacked quantum dots is the answering question of when (i.e. how close) and how (i.e. via electrons or holes) they become electronically coupled. These questions have been answered during the project.

Potential applications of the result:
The result can be applied to further research on quantum dot molecules with relevance for quantum computing. It can also be applied to laser devices in which stacks of dots are used to increase the gain and coupling should be avoided, or for fine tuning of the emission wavelength, when coupling is exploited.

End-users of the result:
The end users of this result are the scientific community and industry (semiconductor laser manufacturers).

Main innovative features/benefits:
The result offers, for the first time, a clear answer to a question of fundamental importance in self-assembled quantum dots.

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

Potential barriers:
There are no potential barriers to the use of this result.
