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…
Activated Transport in the individual Layers that form the =1 Exciton Condensate
R. D. Wiersma, J. G. S. Lok, S. Kraus +6
We observe the total filling factor =1 quantum Hall state in a bilayer two-dimensional electron system with virtually no tunnelling. We find thermally activated transport in…
Coulomb Drag as a Probe of the Nature of Compressible States in a Magnetic Field
K. Muraki, J. G. S. Lok, S. Kraus +5
Magneto-drag reveals the nature of compressible states and the underlying interplay of disorder and interactions. At ν=3/2 a clear T^{4/3} dependence is observed, which signifies t…
Spin effects in the magneto-drag between double quantum wells
J. G. S. Lok, S. Kraus, M. Pohlt +4
We report on the selectivity to spin in a drag measurement. This selectivity to spin causes deep minima in the magneto-drag at odd fillingfactors for matched electron densities at…
