Millisecond spin lifetimes in quantum dots at zero applied magnetic field due to strong electron-nuclear interaction
A. Greilich, R. Oulton, S. Yu. Verbin +7
A key to achieving ultra-long electron spin memory in quantum dots (QDs) at 0~ is the polarization of the nuclei, such that the electron spin is stabilized along the nuclear mag…
Thermopower of a Kondo-correlated quantum dot
R. Scheibner, H. Buhmann, D. Reuter +2
The thermopower of a Kondo-correlated gate-defined quantum dot is studied using a current heating technique. In the presence of spin correlations the thermopower shows a clear devi…
Magnetization of a two-dimensional electron gas with a second filled subband
M. R. Schaapman, U. Zeitler, P. C. M. Christianen +5
We have measured the magnetization of a dual-subband two-dimensional electron gas, confined in a GaAs/AlGaAs heterojunction. In contrast to two-dimensional electron gases with a si…
Phase measurements using Two-Channel Fano Interference in a Semiconductor Quantum Dot
C. Fuhner, U. F. Keyser, R. J. Haug +2
We investigate a lateral semiconductor quantum dot with a large number of electrons in the semi-open Fano regime. In transport measurements we observe three stable series of Fano r…
Aharonov-Bohm cages in the GaAlAs/GaAs system
C. Naud, G. Faini, D. Mailly +5
Aharonov-Bohm oscillations have been observed in a lattice formed by a two dimensional rhombus tiling. This observation is in good agreement with a recent theoretical calculation o…
