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…
"Forbidden" transitions between quantum Hall and insulating phases in p-SiGe heterostructures
M. R. Sakr, Maryam Rahimi, S. V. Kravchenko +3
We show that in dilute metallic p-SiGe heterostructures, magnetic field can cause multiple quantum Hall-insulator-quantum Hall transitions. The insulating states are observed betwe…
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…
