Jens Kunstmann of the Max-Planck Institute in Stuttgart, with colleagues in Germany, Italy, and Turkey, has proposed a “blueprint” for graphene-based nanodevices of the future. The model involves using alternating chains of B7 boron clusters to connect various parts of a semiconducting graphene substrate (boron and carbon are compatible at the nanoscale). The small planar clusters act as metallic islands (i.e., electrically conductive zones) embedded in the graphene substrate, and can allow electron transport through the substrate. The concept is very similar to that routinely employed in silicon-based integrated circuits, but the resulting graphene-based devices would be several orders of magnitude smaller.
