  The intrinsic spin-Hall effect on spin accumulation and electric conductance
in a diffusive regime of a 2D electron gas has been studied for a 2D strip of a
finite width. It is shown that the spin polarization near the flanks of the
strip, as well as the electric current in the longitudinal direction exhibit
damped oscillations as a function of the width and strength of the Dresselhaus
spin-orbit interaction. Cubic terms of this interaction are crucial for spin
accumulation near the edges. As expected, no effect on the spin accumulation
and electric conductance have been found in case of Rashba spin-orbit
interaction.
