“…Recently, it was proposed that the radiation-induced oscillatory magnetoresistance can be used as a sensitive probe of the zero-field spin-splitting [182]. The experimental results indicated that the largest Rashba parameter α R can be 30 × 10 −12 eV m [161,163] or even 40 × 10 −12 eV m [165] for InAs and 14 × 10 −12 eV m for GaSb [180] quantum wells, while the smallest Rashba parameter can be negligible [178,183].…”

This article reviews the current status of spin dynamics in semiconductors which has achieved a lot of progress in the past years due to the fast growing field of semiconductor spintronics. The primary focus is the theoretical and experimental developments of spin relaxation and dephasing in both spin precession in time domain and spin diffusion and transport in spacial domain. A fully microscopic many-body investigation on spin dynamics based on the kinetic spin Bloch equation approach is reviewed comprehensively.Comment: a review article with 193 pages and 1103 references.

“…To shed some light on the physics behind them, a great effort has been made, especially from the experimental side, growing better samples, adding new features and different probes to the basic experimental setup, etc. [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] Of course the experimental results always mean a real challenge for the existent theoretical models. Thus, a comparison of experiment with theory could help to identify the importance of the invoked mechanisms in these theories.…”

We report on theoretical studies of recently discovered microwave-induced resistance oscillations and zeroresistance states in Hall bars with two occupied subbands. In the same results, resistance presents a peculiar shape which appears to have a built-in interference effect not observed before. We apply the microwave-driven electron orbit model, which implies a radiation-driven oscillation of the two-dimensional electron system. Thus, we calculate different intra-and intersubband electron scattering rates and times that are revealing as different microwave-driven oscillation frequencies for the two electronic subbands. Through scattering, these subband-dependent oscillation motions interfere give rise to a striking resistance profile. We also study the dependence of irradiated magnetoresistance with power and temperature. Calculated results are in good agreement with experiments.

“…9,10 The spin-orbit strength can be measured in a variety of different experimental setups: 11 In a magnetoresistance measurement via Shubnikov-de Haas oscillations, 7,8,[12][13][14] weak (anti-) localization, 13,[15][16][17] or electron spin resonances in semiconducting nanostructures [18][19][20][21] or quantum dots, 22 or optically via spin relaxation, 23 spin precession, 18 spin-flip Raman scattering, 24 or radiation-induced magnetoresistance oscillations. 25 In this paper, we propose a method for extracting the strength of the Rashba spin-orbit interaction via a charge conductance measurement. This method does not require the use of external magnetic fields or radiation sources.…”

Rashba spin orbit interaction in a quantum wire superlattice

et al. 2012

In this work, we study the effects of a longitudinal periodic potential on a parabolic quantum wire defined in a two-dimensional electron gas with Rashba spin-orbit interaction. For an infinite wire superlattice we find, by direct diagonalization, that the energy gaps are shifted away from the usual Bragg planes due to the Rashba spin-orbit interaction. Interestingly, our results show that the location of the band gaps in energy can be controlled via the strength of the Rashba spin-orbit interaction. We have also calculated the charge conductance through a periodic potential of a finite length via the nonequilibrium Green's function method combined with the Landauer formalism. We find dips in the conductance that correspond well to the energy gaps of the infinite wire superlattice. From the infinite wire energy dispersion, we derive an equation relating the location of the conductance dips as a function of the (gate controllable) Fermi energy to the Rashba spin-orbit coupling strength. We propose that the strength of the Rashba spin-orbit interaction can be extracted via a charge conductance measurement.
