An electrostatically defined serial triple quantum dot charged with few electrons
D. Schröer, A. D. Greentree, L. Gaudreau +4
A serial triple quantum dot (TQD) electrostatically defined in a GaAs/AlGaAs heterostructure is characterized by using a nearby quantum point contact as charge detector. Ground sta…
A widely tunable few electron droplet
A. K. Huettel, K. Eberl, S. Ludwig
Quasi-static transport measurements are employed to characterize a few electron quantum dot electrostatically defined in a GaAs/AlGaAs heterostructure. The gate geometry allows obs…
Kondo effect in a one-electron double quantum dot: Oscillations of the Kondo current in a weak magnetic field
D. M. Schröer, A. K. Hüttel, K. Eberl +3
We present transport measurements of the Kondo effect in a double quantum dot charged with only one or two electrons, respectively. For the one electron case we observe a surprisin…
Evidence of breakdown of the spin symmetry in diluted 2D electron gases
P. Giudici, A. R. Goñi, P. G. Bolcatto +4
Recent claims of an experimental demonstration of spontaneous spin polarisation in dilute electron gases \cite{young99} revived long standing theoretical discussions \cite{ceper99,…
Jahn-Teller / Kondo Interplay in a Three-Terminal Quantum Dot
Ryan C. Toonen, Hua Qin, Andreas K. Huettel +4
In quantum dot circuits, screening electron clouds in strongly-coupled leads will hybridize with the states of the artificial atom. Using a three-terminal geometry, we directly pro…
Molecular states in a one-electron double quantum dot
A. K. Huettel, S. Ludwig, H. Lorenz +2
The transport spectrum of a strongly tunnel-coupled one-electron double quantum dot electrostatically defined in a GaAs/AlGaAs heterostructure is studied. At finite source-drain-vo…
