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…
Coherent Aharonov Bohm oscillations in type-II (ZnMn)Te quantum dots
I. R. Sellers, V. R. Whiteside, A. O. Govorov +5
The magneto-photoluminescence of type-II (ZnMn)Te quantum dots is presented. As a result of the type-II band alignment Aharonov-Bohm (AB) oscillations in the photoluminescence inte…
Kondo-excitons and Auger processes in self-assembled quantum dots
A. O. Govorov, K. Karrai, R. J. Warburton +1
We describe theoretically novel excitons in self-assembled quantum dots interacting with a two-dimensional electron gas in the wetting layer. In the presence of the Fermi sea, the…
Nonlinear acousto-electric transport in a two-dimensional electron system
A. O. Govorov, A. V. Kalameitsev, M. Rotter +4
We study both theoretically and experimentally the nonlinear interaction between an intense surface acoustic wave and a two-dimensional electron plasma in semiconductor-piezocrysta…
