Spin-independent origin of the strongly enhanced effective mass in a dilute 2D electron system
A. A. Shashkin, Maryam Rahimi, S. Anissimova +3
We have accurately measured the effective mass in a dilute two-dimensional electron system in silicon by analyzing temperature dependence of the Shubnikov-de Haas oscillations in t…
Coherent back-scattering near the two-dimensional metal-insulator transition
Maryam Rahimi, S. Anissimova, M. R. Sakr +2
We have studied corrections to conductivity due to the coherent backscattering in low-disordered two-dimensional electron systems in silicon for a range of electron densities inclu…
Compressibility of a two-dimensional hole gas in tilted magnetic field
Maryam Rahimi, M. R. Sakr, S. V. Kravchenko +2
We have measured compressibility of a two-dimensional hole gas in p-GaAs/AlGaAs heterostructure, grown on a (100) surface, in the presence of a tilted magnetic field. It turns out…
"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…
Fate of the extended states in a vanishing magnetic field: the role of spins in strongly-interacting 2D electron systems
M. R. Sakr, Maryam Rahimi, S. V. Kravchenko
In non-interacting or weakly-interacting 2D electron systems, the energy of the extended states increases as the perpendicular magnetic field approaches zero: the extended states "…
