Abstract
The influence of inhomogeneous Rashba interaction on spin-transport of two-dimensional electron gas system (2DEG) is investigated. In the works which have been previously performed in this field it has been shown that in the non-equilibrium regime, the Rashba and Dresselhaus couplings cannot be responsible for spin-current and both transverse and longitudinal components of the spin-current identically vanish. In the present work by using a semi-classical method it was found out that a random Rashba field interaction cannot be considered as a underestimate effect on spin-dependent mechanisms. Regarding the inhomogeneous distribution of the Rashba field it was shown that the spin-current of the system, in general, does not go all the way to zero.
