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…
Excited State Quantum Couplings and Optical Switching of an Artificial Molecule
K. Müller, G. Reithmaier, E. C. Clark +6
We optically probe the spectrum of ground and excited state transitions of an individual, electrically tunable self-assembled quantum dot molecule. Photocurrent absorption measurem…
Shape control of QDs studied by cross-sectional scanning tunneling microscopy
J. G. Keizer, M. Bozkurt, J. Bocquel +12
In this cross-sectional scanning tunneling microscopy study we investigated various techniques to control the shape of self-assembled quantum dots (QDs) and wetting layers (WLs). T…
Electrical control of the exciton-biexciton splitting in a single self-assembled InGaAs quantum dots
M. Kaniber, M. F. Huck, K. Müller +5
We report on single InGaAs quantum dots embedded in a lateral electric field device. By applying a voltage we tune the neutral exciton transition into resonance with the biexciton…
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…
