Carbon Ion Beam Growth of Isotopically-Enriched Graphene and Isotope-Junctions
Isotopically-enriched graphene and isotope junctions are epitaxially grown on a catalyst substrate using a focused carbon ion beam technique. The focused carbon ion beam is filtered to pass substantially a single ion species including a single desired carbon isotope. The ion beam and filtering together provide a means to selectively isotopically-enrich...

Fabrication of Pillared Graphene
This invention is a method of fabricating pillared graphene. This is accomplished by first constraining a layer of fullerenes between graphene sheets (the proto structure). Tether molecules may be employed to help chemically bind the fullerenes to the graphene at attachment points. Energy is applied to the proto structure via chemical reaction, thermal...
