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…
On the relation between the 0.7-anomaly and the Kondo effect: Geometric Crossover between a Quantum Point Contact and a Kondo Quantum Dot
Jan Heyder, Florian Bauer, Enrico Schubert +5
Quantum point contacts (QPCs) and quantum dots (QDs), two elementary building blocks of semiconducting nanodevices, both exhibit famously anomalous conductance features: the 0.7-an…
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…
Towards combined transport and optical studies of the 0.7-anomaly in a quantum point contact
E. Schubert, J. Heyder, F. Bauer +5
A Quantum Point Contact (QPC) causes a one-dimensional constriction on the spatial potential landscape of a two-dimensional electron system. By tuning the voltage applied on a QPC…
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…
