Coulomb mediated hybridization of excitons in artificial molecules
P. -L. Ardelt, K. Gawarecki, K. Müller +11
We report the Coulomb mediated hybridization of excitonic states in an optically active, artificial quantum dot molecule. By probing the optical response of the artificial molecule…
Highly Non-linear Excitonic Zeeman Spin-Splitting in Composition-Engineered Artificial Atoms
V. Jovanov, T. Eissfeller, S. Kapfinger +8
Non-linear Zeeman splitting of neutral excitons is observed in composition engineered In(x)Ga(1-x)As self-assembled quantum dots and its microscopic origin is explained. Eight-band…
Coplanar stripline antenna design for optically detected magnetic resonance on semiconductor quantum dots
F. Klotz, H. Huebl, D. Heiss +3
We report on the development and testing of a coplanar stripline antenna that is designed for integration in a magneto-photoluminescence experiment to allow coherent control of ind…
Probing spin relaxation in an individual InGaAs quantum dot using a single electron optical spin memory device
D. Heiss, V. Jovanov, F. Klotz +5
We demonstrate all optical electron spin initialization, storage and readout in a single self-assembled InGaAs quantum dot. Using a single dot charge storage device we monitor the…
Strong electrically tunable exciton g-factors in an individual quantum dots due to hole orbital angular momentum quenching
V. Jovanov, T. Eissfeller, S. Kapfinger +4
Strong electrically tunable exciton g-factors are observed in individual (Ga)InAs self-assembled quantum dots and the microscopic origin of the effect is explained. Realistic eight…
Asymmetric optical nuclear spin pumping in a single uncharged quantum dot
F. Klotz, V. Jovanov, J. Kierig +7
A highly asymmetric dynamic nuclear spin pumping is observed in a single self assembled InGaAs quantum dot subject to resonant optical pumping of the neutral exciton transition lea…
