Current-induced asymmetries of incompressible stripes in narrow quantum Hall systems
Rolf R. Gerhardts, Konstantinos Panos, Jürgen Weis
We present recent experimental results confirming previously predicted strong asymmetries of the current distribution in narrow Hall bars under the conditions of the integer quantu…
Local density of states of two-dimensional electron systems under strong in-plane electric and perpendicular magnetic fields
S. Erden Gulebaglan, I. Sokmen, A. Siddiki +1
We calculate the local density of states of a two-dimensional electron system under strong crossed magnetic and electric fields. We assume a strong perpendicular magnetic field whi…
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…
The Interrelation between Incompressible Strips and Quantized Hall Plateaus
Afif Siddiki, Rolf R. Gerhardts
We study the current and charge distribution of a two dimensional electron gas under strong perpendicular magnetic fields within the linear response regime. We show within a self-c…
Incompressible strips in dissipative Hall bars as origin of quantized Hall plateaus
Afif Siddiki, Rolf R. Gerhardts
We study the current and charge distribution in a two dimensional electron system, under the conditions of the integer quantized Hall effect, on the basis of a quasi-local transpor…
Thomas-Fermi-Poisson theory of screening for latterally confined and unconfined two-dimensional electron systems in strong magnetic fields
A. Siddiki, Rolf R. Gerhardts
We examine within the self-consistent Thomas-Fermi-Poisson approach the low-temperature screening properties of a two-dimensional electron gas (2DEG) subjected to strong perpendicu…
