摘      要：We investigate theoretically the spin accumulation in a Rashba spin-orbit coupling (SOC) nanoribbon nonadiabatically connected to a normal *** the nanoribbon and conductor are described by a hard-wall confining *** the scattering matrix approach within the effective free-electron approximation,we have calculated the out-of-plane spin accumulation in the *** is found that the spin accumulation shifts toward the two edges of nanoribbon with the increasing of propagation ***,as the Rashba SOC strength increases the spin accumulation in the nanoribbon will be enhanced and this result may suggest us a simple method to control the spin accumulation of the system by Rashba SOC strength.
