Fine structure of phonon replicas in a tunnel spectrum of a GaAs quantum well
V. G. Krishtop, V. G. Popov, M. Henini +2
A fine structure of phonon replicas in the current-voltage characteristic of a resonant-tunneling diode has been investigated experimentally. A detailed study of the diode I-V curv…
Dispersive line shape in the vicinity of the ν = 1 quantum Hall state: Coexistence of Knight shifted and unshifted resistively detected NMR responses
W. Desrat, B. A. Piot, S. Krämer +4
The frequency splitting between the dip and the peak of the resistively detected nuclear magnetic resonance (RDNMR) dispersive line shape (DLS) has been measured in the quantum Hal…
Classical percolation fingerprints in the high-temperature regime of the integer quantum Hall effect
M. Flöser, B. A. Piot, C. L. Campbell +6
We have performed magnetotransport experiments in the high-temperature regime (up to 50 K) of the integer quantum Hall effect for two-dimensional electron gases in semiconducting h…
Real-space imaging of quantum Hall effect edge strips
M. E. Suddards, A. Baumgartner, M. Henini +1
We use dynamic scanning capacitance microscopy (DSCM) to image compressible and incompressible strips at the edge of a Hall bar in a two-dimensional electron gas (2DEG) in the quan…
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…
Electric field inversion asymmetry: Rashba and Stark effects for holes in resonant tunneling devices
H. B. de Carvalho, M. J. S. P. Brasil, V. Lopez-Richard +7
We report experimental evidence of excitonic spin-splitting, in addition to the conventional Zeeman effect, produced by a combination of the Rashba spin-orbit interaction, Stark sh…
