All-graphene edge contacts: Electrical resistance of graphene T-junctions [PDF]

, 2016
Using ab-initio methods we investigate the possibility of three-terminal graphene "T-junction" devices and show that these all-graphene edge contacts are energetically feasible when the 1D interface itself is free from foreign atoms.
