Influence of the charge carrier tunneling processes on the recombination dynamics in single lateral quantum dot molecules
C. Hermannstädter, G. J. Beirne, M. Witzany +7
We report on the charge carrier dynamics in single lateral quantum dot molecules and the effect of an applied electric field on the molecular states. Controllable electron tunnelin…

Heterogeneous confinement in laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric fields
Jie Peng, Claus Hermannstädter, Marcus Witzany +7
We study the electronic and optical properties of laterally coupled InGaAs/GaAs quantum dot molecules under lateral electric field. We find that electrons perceive the double-dot s…

Polarization fine-structure and enhanced single-photon emission of self-assembled lateral InGaAs quantum dot molecules embedded in a planar micro-cavity
C. Hermannstädter, M. Witzany, G. J. Beirne +8
Single lateral InGaAs quantum dot molecules have been embedded in a planar micro-cavity in order to increase the luminescence extraction efficiency. Using a combination of metal-or…
