Ambipolar spin diffusion and D’yakonov-Perel’ spin relaxation in GaAs quantum wells
We report theoretical and experimental studies of ambipolar spin diffusion in a semiconductor. A circularly polarized laser pulse is used to excite spin-polarized carriers in a GaAs multiple quantum-well sample at 80 K. Diffusion of electron and spin densities is simultaneously measured using a spatially and temporally resolved pump-probe technique. Two regimes of diffusion for spin-polarized e...
متن کاملSpin-orbit coupling in bulk GaAs
We study the spin-orbit coupling in the whole Brillouin zone for GaAs using both the spsd and sps nearest-neighbor tight-binding models. In the Γ-valley, the spin splitting obtained is in good agreement with experimental data. We then further explicitly present the coefficients of the spin splitting in GaAs L and X valleys. These results are important to the realization of spintronic device and...
متن کاملJHH Spin-Spin Coupling Constants
Some calculations of the electric field derivative of the spin-spin coupling constant on molecules in the series CH3F, CH3Cl, CH3Br, CH3I, CH4, CH3Li, CH3Na and CH3K have been presented. The data is broken down into the 4 terms of the Ramsey theory: Fermi contact (FC); diamagnetic spin-orbit (DSO); paramagnetic spinorbit (PSO) and spin-dipolar (SD). The FC term is seen to dominate all the calcu...
متن کاملSpin transport through GaAs/GaMnAs/GaAs
This work addresses spin-dependent transport in the heterostructure p-GaAs/GaMnAs/p-GaAs. The diluted ferromagnetic semiconductor GaMnAs layer behaves, within mean field approximation, as a potential well for spin-down carriers and a potential barrier for spin-up ones. Thus the transport would be spin-dependent. The goal of this work is to devise spin filters relevant for spin-dependent optoele...
متن کاملSpin–spin Coupling in the Solar System
The richness of dynamical behavior exhibited by the rotational states of various solar system objects has driven significant advances in the theoretical understanding of their evolutionary histories. An important factor that determines whether a given object is prone to exhibiting non-trivial rotational evolution is the extent to which such an object can maintain a permanent aspheroidal shape, ...
