Confocal shift interferometry of coherent emission from trapped dipolar excitons
Jens Repp, Georg J. Schinner, Enrico Schubert +6
We introduce a confocal shift-interferometer based on optical fibers. The presented spectroscopy allows measuring coherence maps of luminescent samples with a high spatial resoluti…
Sub-Kelvin optical thermometry of an electron reservoir coupled to a self-assembled InGaAs quantum dot
F. Seilmeier, M. Hauck, E. Schubert +3
We show how resonant laser spectroscopy of the trion optical transitions in a self-assembled quantum dot can be used to determine the temperature of a nearby electron reservoir. At…
Single exciton emission from gate-defined quantum dots
G. J. Schinner, J. Repp, E. Schubert +6
With gate-defined electrostatic traps fabricated on a double quantum well we are able to realize an optically active and voltage-tunable quantum dot confining individual, long-livi…
Many-body correlations of electrostatically trapped dipolar excitons
G. J. Schinner, J. Repp, E. Schubert +6
We study the photoluminescence (PL) of a two-dimensional liquid of oriented dipolar excitons in In_{x}Ga_{1-x}As coupled double quantum wells confined to a microtrap. Generating ex…
Relaxation of hot electrons in a degenerate two-dimensional electron system: transition to one-dimensional scattering
D. Taubert, C. Tomaras, G. J. Schinner +4
The energy relaxation channels of hot electrons far from thermal equilibrium in a degenerate two-dimensional electron system are investigated in transport experiments in a mesoscop…
An electron jet pump: The Venturi effect of a Fermi liquid
D. Taubert, G. J. Schinner, C. Tomaras +3
A three-terminal device based on a two-dimensional electron system is investigated in the regime of non-equilibrium transport. Excited electrons scatter with the cold Fermi sea and…
