Magnetic anisotropy in (Ga,Mn)As: Influence of epitaxial strain and hole concentration
M. Glunk, J. Daeubler, L. Dreher +8
We present a systematic study on the influence of epitaxial strain and hole concentration on the magnetic anisotropy in (Ga,Mn)As at 4.2 K. The strain was gradually varied over a w…
Gate control of low-temperature spin dynamics in two-dimensional hole systems
M. Kugler, T. Andlauer, T. Korn +9
We have investigated spin and carrier dynamics of resident holes in high-mobility two-dimensional hole systems in GaAs/AlGaAs single quantum wells at temperatures d…
Coherent potential approximation for spatially correlated disorder
Roland Zimmermann, Christoph Schindler
The coherent potential approximation (CPA) is extended to describe satisfactorily the motion of particles in a random potential which is spatially correlated and smoothly varying.…
Density Enhanced Diffusion of Dipolar Excitons within a One-Dimensional Channel
X. P. Vogele, D. Schuh, W. Wegscheider +2
We experimentally investigate the lateral diffusion of dipolar excitons in coupled quantum wells in two (2D) and one (1D) dimensions. In 2D, the exciton expansion obeys non-linear…
Selective Optical Charge Generation, Storage and Readout in a Single Self Assembled Quantum Dot
D. Heiss, V. Jovanov, M. Caesar +3
We report the investigation of a single quantum dot charge storage device. The device allows selective optical charging of a single dot with electrons, storage of these charges ove…
A Schottky top-gated two-dimensional electron system in a nuclear spin free Si/SiGe heterostructure
J. Sailer, V. Lang, G. Abstreiter +8
We report on the realization and top-gating of a two-dimensional electron system in a nuclear spin free environment using 28Si and 70Ge source material in molecular beam epitaxy. E…
