Series of magnetoresistance oscillations of a two-dimensional electron gas in a strong periodic magnetic modulation
A nonperturbative technique is used to calculate the magnetoresistance of two-dimensional electron gases ~2DEG! subjected to a spatially periodic magnetic field B1 with period a in addition to a uniform magnetic field B0 in the same direction. For small amplitude modulation, magnetoresistance exhibits oscillations similar to the Weiss oscillations observed in 2DEG under spatially periodic elect...
متن کاملQuantum transport theory of Weiss oscillations quenching of a two-dimensional electron gas in a strong periodic potential.
The quenching of the Weiss oscillation of magnetoresistance in a two-dimensional electron gas subjected to strong one-dimensional periodic potential is calculated nonperturbatively using quantum transport theory. The results are in good qualitative agreement with the experiment of Beton et al. @Phys. Rev. B 42, 9229 ~1990!#. The discrepancy between the classical calculation and the experiment i...
متن کاملBallistic spin transport in a two-dimensional electron gas
We explore electrically injected, spin-polarized transport in a ballistic two-dimensional electron gas. We augment the Büttiker-Landauer picture with a simple, but realistic model for spin-selective contacts to describe multimode reservoir-to-reservoir transport of ballistic spin-1/2 particles. Clear and unambiguous signatures of spin transport are established in this regime, for the simplest m...
متن کاملKinetic Transport in the Two-dimensional Periodic Lorentz Gas
Abstract. The periodic Lorentz gas describes an ensemble of non-interacting point particles in a periodic array of spherical scatterers. We have recently shown that, in the limit of small scatterer density (Boltzmann-Grad limit), the macroscopic dynamics converges to a stochastic process, whose kinetic transport equation is not the linear Boltzmann equation—in contrast to the Lorentz gas with a...
متن کاملHall Conductance of a Two-Dimensional Electron Gas with Spin-Orbit Coupling at the Presence of Lateral Periodic Potential
We evaluate the distribution of Hall conductances in magnetic subbands of two-dimensional electron gas with Rashba spin-orbit (SO) coupling placed in a periodic potential and perpendicular magnetic field. In this semiconductor structure the spin-orbit coupling mixes the states of different magnetic subbands and changes the distribution of their Hall conductances in comparison with the case of s...
