RESUMO
We study the ballistic transmission and the contact resistance (R c) of a graphite-graphene contact in a top contact geometry from first principles. We find that the calculated R c's depend on the amount of graphene-graphite overlap, but quickly saturate for transfer lengths of the order of a few tens of Å. For contacts overlapping more than this transfer length, the R c can be lower than the 100 [Formula: see text] mark. On the other hand, edge graphite-graphene contacts are expected to have very low contact resistance.
