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…
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…
