Magnetotransport of electrons in quantum Hall systems
I. A. Dmitriev, F. Evers, I. V. Gornyi +3
Recent theoretical results on magnetotransport of electrons in a 2D system in the range of moderately strong transverse magnetic fields are reviewed. The phenomena discussed includ…
The tensor of interaction of a two-level system with an arbitrary strain field
D. V. Anghel, T. Kühn, Y. M. Galperin +1
The interaction between two-level systems (TLS) and strain fields in a solid is contained in the diagonal matrix element of the interaction hamiltonian, , which, in general, has…
Sharp Magnetic Field Dependence of the 2D Hall Coefficient Induced by Classical Memory Effects
A. P. Dmitriev, V. Yu. Kachorovskii
We show that a sharp dependence of the Hall coefficient on the magnetic field arises in two-dimensional electron systems with randomly located strong scatterers. The phenom…
Slow relaxation of conductance of amorphous hopping insulators
A. L. Burin, V. I. Kozub, Y. M. Galperin +1
We discuss memory effects in the conductance of hopping insulators due to slow rearrangements of structural defects leading to formation of polarons close to the electron hopping s…
Intervalley scattering and weak localization in Si-based two-dimensional structures
A. Yu. Kuntsevich, N. N. Klimov, S. A. Tarasenko +4
We have measured the weak localization magnetoresistance in (001)-oriented Si MOS structures with a wide range of mobilities. For the quantitative analysis of the data, we have ext…
