附注	the magnetic and spin dependent transport properties of asymmetrically hydrogenated zigzag graphene nanoribbons, which are c-h2 bonded at one edge while c-h bonded at the other, are investigated from first-principles calculations. due to their special distributions of the density of states near fermi level, a perfect (100%) spin filtering effect can be achieved in such graphene nanoribbons through p-type or n-type doping. moreover, a negative differential resistance effect is observed in both doping case, which results from the reducing of conductance near fermi level with increasing bias voltage.
