Scalable templated growth of graphene nanoribbons on SiC: Direct nanoribbon growth avoids the need for damaging post-processing.
• Self-organized growth of graphene nanoribbons
(as narrow as 40 nm) at specified positions on templated SiC substrate prepared using scalable photolithography and microelectronics processing.
• Prototype graphene devices exhibit ballistic transport at low temperatures, an on–off ratio of 10.
