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…
Wigner Crystallization in a Quasi-3D Electronic System
B. A. Piot, Z. Jiang, C. R. Dean +4
When a strong magnetic field is applied perpendicularly (along z) to a sheet confining electrons to two dimensions (x-y), highly correlated states emerge as a result of the interpl…
Contrasting Behavior of the 5/2 and 7/3 Fractional Quantum Hall Effect in a Tilted Field
C. R. Dean, B. A. Piot, P. Hayden +4
Using a tilted field geometry, the effect of an in-plane magnetic field on the even denominator nu = 5/2 fractional quantum Hall state is studied. The energy gap of the nu = 5/2 st…
Intrinsic Gap of the nu=5/2 Fractional Quantum Hall State
C. R. Dean, B. A. Piot, P. Hayden +4
The fractional quantum Hall effect is observed at low field, in a regime where the cyclotron energy is smaller than the Coulomb interaction. The nu=5/2 excitation gap is measured t…
Resistively Detected NMR in Quantum Hall States: Investigation of the anomalous lineshape near
C. R. Dean, B. A. Piot, L. N. Pfeiffer +2
A study of the resistively detected nuclear magnetic resonance (RDNMR) lineshape in the vicinity of was performed on a high-mobility 2D electron gas formed in GaAs/AlGaAs. In…
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…
