Shifting the quantum Hall plateau level in a double layer electron system
E. V. Deviatov, A. A. Shashkin, V. T. Dolgopolov +4
We study the plateaux of the integer quantum Hall resistance in a bilayer electron system in tilted magnetic fields. In a narrow range of tilt angles and at certain magnetic fields…
Sharp increase of the effective mass near the critical density in a metallic 2D electron system
A. A. Shashkin, S. V. Kravchenko, V. T. Dolgopolov +1
We find that at intermediate temperatures, the metallic temperature dependence of the conductivity σ(T) of 2D electrons in silicon is described well by a recent interaction-based t…
Separately contacted edge states: A new spectroscopic tool for the investigation of the quantum Hall effect
A. Wuertz, R. Wildfeuer, A. Lorke +2
Using an innovative combination of a quasi-Corbino sample geometry and the cross-gate technique, we have developed a method that enables us to separately contact single edge channe…
Comment on "Low-Density Spin Susceptibility and Effective Mass of Mobile Electrons in Si Inversion Layers"
S. V. Kravchenko, A. A. Shashkin, V. T. Dolgopolov
In a recent Letter (PRL 88, 196404 (2002)), the effective g-factor and the effective mass have been studied by Pudalov et al. in a dilute 2D electron system in silicon. The authors…
Quantization of the Hall conductivity well beyond the adiabatic limit in pulsed magnetic fields
V. T. Dolgopolov, A. A. Shashkin, J. M. Broto +2
We measure the Hall conductivity, , on a Corbino geometry sample of a high-mobility AlGaAs/GaAs heterostructure in a pulsed magnetic field. At a bath temperature about 80 m…
