Asymmetric non-linear response of the IQHE
A. Siddiki, J. Horas, D. Kupidura +2
An asymmetric break-down of the integer quantized Hall effect is investigated. This rectification effect is observed as a function of the current value and its direction in conjunc…

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…

Probing a Kondo correlated quantum dot with spin spectroscopy
D. Kupidura, M. C. Rogge, M. Reinwald +2
We investigate Kondo effect and spin blockade observed on a many-electron quantum dot and study the magnetic field dependence. At lower fields a pronounced Kondo effect is found wh…
