Interplay among spin, orbital effects and localization in a GaAs two-dimensional electron gas in a strong in-plane magnetic field
B. A. Piot, D. K. Maude, U. Gennser +2
The magnetoresistance of a low carrier density, disordered GaAs based two-dimensional (2D) electron gas has been measured in parallel magnetic fields up to 32 T. The feature in the…
Magnetoresistance of antidot lattices with grain boundaries
S. Klinkhammer, Hengyi Xu, T. Heinzel +4
The magnetotransport properties of antidot lattices containing artificially designed grain boundaries have been measured. We find that the grain boundaries broaden the commensurabi…
Noise dephasing in the edge states of the Integer Quantum Hall regime
P. Roulleau, F. Portier, P. Roche +4
An electronic Mach Zehnder interferometer is used in the integer quantum hall regime at filling factor 2, to study the dephasing of the interferences. This is found to be induced b…
Direct measurement of the coherence length of edge states in the Integer Quantum Hall Regime
P. Roulleau, F. Portier, P. Roche +4
We have determined the finite temperature coherence length of edge states in the Integer Quantum Hall Effect (IQHE) regime. This was realized by measuring the visibility of electro…
Influence of the single-particle Zeeman energy on the quantum Hall ferromagnet at high filling factors
B. A. Piot, D. K. Maude, M. Henini +10
In a recent paper [B. A. Piot et al., Phys. Rev. B 72, 245325 (2005)], we have shown that the lifting of the electron spin degeneracy in the integer quantum Hall effect at high fil…
