We theoretically propose a graphene-based adiabatic quantum pump withintrinsic spin-orbit coupling (SOC) subject to strain where two time-dependentextrinsic spin-orbit coupled barriers drive spin and charge currents. We studythree differing operation modes where i) location, ii) chemical potential, andiii) SOC of the two barriers oscillate periodically and out of phase aroundtheir equilibrium states. Our results demonstrate that the amplitude ofadiabatically pumped currents highly depends on the considered operation mode.We find that such a device operates with highest efficiency and in a broaderrange of parameters where the barriers chemical potential drives the quantumpump. Our results also reveal that by introducing strain to the system, one cansuppress or enhance the charge and spin currents separately, depending onstrain direction.
