Dynamics of bright and dark excitons in a self-assembled quantum dot
- Abstract:
-
We report on a spin-flip process in a charge tunable quantum dot in which a non-radiative dark exciton, with angular momentum L = 2, becomes a radiative bright exciton, L = 1, through interactions with a Fermi sea in an n-doped back contact. This process presents itself by a strongly bias dependent secondary lifetime in radiative lifetime measurements of the neutral exciton. By studying dots with different emission energies the spin-flip process is shown to have a strong dependence on the tun...

) if you have queries regarding unavailable content OR if you are aware of a full-text copy we can make available.
Content may be unavailable for the following four reasons
-
Version unsuitable
-
We have not obtained a suitable full-text for a given research output. See this page for more information.
-

Clearance
-
Some thesis volumes scanned as part of the digitisation scheme funded by Dr Leonard Polonsky are currently unavailable due to sensitive material or uncleared third-party copyright content. We are attempting to contact authors whose theses are affected.
Alternative access to the full-text
You may be able to access the full-text directly from the publisher's website using the 'Publisher Copy' link in the 'Links & Downloads' box from a research output's ORA record page. This method may require an institutional or individual subscription to the journal/resource.
