Recent advances in exciton based quantum information processing in quantum dot nanostructures
H. J. Krenner, S. Stufler, M. Sabathil +6
Recent experimental developments in the field of semiconductor quantum dot spectroscopy will be discussed. First we report about single quantum dot exciton two-level systems and th…
Direct Observation of Controlled Coupling in an Individual Quantum Dot Molecule
H. J. Krenner, M. Sabathil, E. C. Clark +5
We report the direct observation of quantum coupling in individual quantum dot molecules and its manipulation using static electric fields. A pronounced anti-crossing of different…
A new method to epitaxially grow long-range ordered self-assembled InAs quantum dots on (110) GaAs
J. Bauer, D. Schuh, E. Uccelli +5
We report on a new approach for positioning of self-assembled InAs quantum dots on (110) GaAs with nanometer precision. By combining self-assembly of quantum dots with molecular be…
Remote-doping scattering and the local field corrections in the 2D electron system in a modulation-doped Si/SiGe quantum well
V. T. Dolgopolov, E. V. Deviatov, A. A. Shashkin +4
The small, about 30% magnetoresistance at the onset of full spin polarization in the 2D electron system in a modulation-doped Si/SiGe quantum well gives evidence that it is the rem…
Combined atomic force microscope and electron-beam lithography used for the fabrication of variable-coupling quantum dots
M. C. Rogge, C. Fuehner, U. F. Keyser +4
We have combined direct nanofabrication by local anodic oxidation with conventional electron-beam lithography to produce a parallel double quantum dot based on a GaAs/AlGaAs hetero…
Spin-photocurrent in p-SiGe quantum wells under terahertz laser irradiation
V. V. Bel'kov, S. D. Ganichev, Petra Schneider +7
A detailed study of the circular photogalvanic effect (CPGE) in SiGe structures is presented. It is shown that the CPGE becomes possible due to the built-in asymmetry of quantum we…
