We present results from an ab initio study of metallized semiconducting graphene nanostructures. Our model system consists of an alternating chain of quasi– planar B7 clusters embedded into a semiconducting armchair nanoribbon. We observe the appearance of overlapping bands around the Fermi‐level, with crystal momenta pointing into the direction of these boron chains. This observation could be a vantage point for the development of graphene nanodevices and integrated nanocircuits, based on existing technologies. Unit cell of B7‐doped armchair graphene nanoribbon.
