Spin Scattering

Doping of silicon with bismuth leads to additional spin scattering of the conduction electron by the spin-orbit potential introduced by a heavy donor. In this paper, we discuss spin flip scattering influence on the generation of spin currents in silicon with electronic conductivity. Based on the theory of spin pumping and the diffusion model, the values of spin currents and voltages of the ISHE are calculated with varying the type of donor and its concentration and the spin diffusion lengths. Calculations made it possible to find the dependences of the magnitudes of the effects on the parameters of silicon layers doped with bismuth, and to explain the absence of ISHE signals when the silicon layer is doped only with phosphorus or antimony with a concentration of Nd> 1019 cm-3.

We investigate the quantum adiabatic pumping effect in an interferometer attached to two one-dimensional leads. The interferometer is subjected to an Aharonov-Bohm flux and Rashba-Dresselhaus spin-orbit interaction. Using Brouwer’s formula and rigorous scattering eigenstates, we obtained the general closed formula for the pumping Berry curvatures depending on spin for general interferometers when the external control parameters only modulate the scattering eigenstates and corresponding eigenvalues. In this situation, pumping effect is absent in the combination of the control parameters of Aharonov-Bohm flux and spin-orbit interaction strength. We have shown that finite pumping is possible by modulating both Rashba and Dresselhaus interaction strengths and explicitly demonstrated the spin-pumping effect in a diamond-shaped interferometer made of four sites.
