In the current work, based on a semiclassical Boltzmann approach, we have investigated the
influence of the Rashba spin-orbit coupling on spin-current of a single layer gapped graphene. It was
shown that the Rashba coupling plays a considerable role in the generation of the spin-current of vertical
spins in mono-layer graphene. The behavior of the spin-current is determined by the density of impurities.
It was also shown that the spin-current of the system could increase by increasing the Rashba coupling
strength and band-gap of the graphene and the sign of the spin-current could be controlled by the direction
of the current-driving electric field.
