|Issue Date:||1-Apr-2012||Citation:||Ho, C.S., Jalil, M.B.A., Tan, S.G. (2012-04-01). Sustainable spin current in the time-dependent Rashba system. Journal of Applied Physics 111 (7) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3693662||Abstract:||The generation of spin current and spin polarization in 2DEG Rashba system is considered, in which the spin-orbital coupling (SOC) is modulated by an ac gate voltage. By using non-Abelian gauge field method, we show the presence of an additional electric field. This field induces a spin current generated even in the presence of impurity scattering and is related to the time-modulation of the Rashba SOC strength. In addition, the spin precession can be controlled by modulating the modulation frequency of the Rashba SOC strength. It is shown that at high modulation frequency, the precessional motion is suppressed so that the electron spin polarization can be sustained in the 2DEG. © 2012 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/71908||ISSN:||00218979||DOI:||10.1063/1.3693662|
