Dephasing by electron-electron interactions in a ballistic Mach-Zehnder interferometer
Clemens Neuenhahn, Florian Marquardt
We consider a ballistic Mach-Zehnder interferometer for electrons propagating chirally in one dimension (such as in an integer Quantum Hall effect edge channel). In such a system,…

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…

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…
