Microwave induced magnetoresistance oscillations at the subharmonics of the cyclotron resonance

S. I. Dorozhkin, J. H. Smet, K. von Klitzing +2

The magnetoresistance oscillations, which occur in a two-dimensional electron system exposed to strong microwave radiation when the microwave frequency coincides with the n-th…

Range-Dependent Disorder Effects on the Plateau-Widths Calculated within the Screening Theory of the Iqhe

Afif Siddiki, Rolf R Gerhardts

We summarize the screening theory of the integer quantized Hall effect (IQHE) and emphasize its two key mechanisms: first, the existence, in certain magnetic field intervals, of in…

Screening Model of Magnetotransport Hysteresis Observed in Bilayer Quantum Hall Systems

Afif Siddiki, Stefan Kraus, Rolf R. Gerhardts

We report on theoretical and experimental investigations of a novel hysteresis effect that has been observed on the magnetoresistance of quantum-Hall bilayer systems. Extending to…

A widely tunable few electron droplet

A. K. Huettel, K. Eberl, S. Ludwig

Quasi-static transport measurements are employed to characterize a few electron quantum dot electrostatically defined in a GaAs/AlGaAs heterostructure. The gate geometry allows obs…

Kondo effect in a one-electron double quantum dot: Oscillations of the Kondo current in a weak magnetic field

D. M. Schröer, A. K. Hüttel, K. Eberl +3

We present transport measurements of the Kondo effect in a double quantum dot charged with only one or two electrons, respectively. For the one electron case we observe a surprisin…
