Nonequilibrium interactions between two quantum circuits
V. S. Khrapai, S. Ludwig, J. P. Kotthaus +2
We briefly overview our recent results on nonequilibrium interactions between neighboring electrically isolated nanostructures. One of the nanostructures is represented by an exter…
Laterally defined freely suspended quantum dots in GaAs/AlGaAs heterostructures
C Rossler, M Bichler, D Schuh +2
Free standing beams containing a two-dimensional electron system are shaped from a GaAs/AlGaAs heterostructure. Quantum point contacts and (double) quantum dots are laterally defin…
Single electron-phonon interaction in a suspended quantum dot phonon cavity
E. M. Höhberger, R. H. Blick, T. Brandes +4
An electron-phonon cavity consisting of a quantum dot embedded in a free-standing GaAs/AlGaAs membrane is characterized in Coulomb blockade measurements at low temperatures. We fin…
Kondo effect in a few-electron quantum ring
U. F. Keyser, C. Fuhner, S. Borck +4
A small quantum ring with less than 10 electrons was studied by transport spectroscopy. For strong coupling to the leads a Kondo effect is observed and used to characterize the spi…
Spin effects in the magneto-drag between double quantum wells
J. G. S. Lok, S. Kraus, M. Pohlt +4
We report on the selectivity to spin in a drag measurement. This selectivity to spin causes deep minima in the magneto-drag at odd fillingfactors for matched electron densities at…
Lateral tunneling through the controlled barrier between edge channels in a two-dimentional electron system
A. A. Shashkin, V. T. Dolgopolov, E. V. Deviatov +5
We study the lateral tunneling through the gate-voltage-controlled barrier, which arises as a result of partial elimination of the donor layer of a heterostructure along a fine str…
