▎ 摘 要
We report the geometrical, electronic and magnetic behaviors for the transition metal vanadium atom absorption on graphene under the applied electric field by using density functional theory. It is found that the structural parameters and binding energies depend on the amplitude and direction of the electric field. In particular, the magnetic moment and work function of a single V adatom on a graphene sheet vary with the amplitude of the electric field. Our studies indicate that direct control of the magnetic properties of a V-graphene sheet can be obtained by an external electric field, suggesting a new avenue for the tunable graphene-based spintronic transport devices.
