Graphene is attractive for spintronics due to spin transport at room temperature with long spin diffusion lengths. During this grant period, two important aspects have been investigated 1 Spin injection and transport in graphene, 2 Spin and charge transport in doped graphene. Main results include the first demonstration of tunneling spin injection into graphene, identification of contact effects as a major source of spin relaxation, realization of high spin injection efficiency, long spin lifetimes in bilayer graphene, the first in-situ transport study of transition metal doping of graphene including studies on graphene spin valves. These results have been at the forefront of graphene spintronics.
