Graphene nanoribbons (GNRs) are the counterpart of nanotubes in graphene nanoelectronics. The search for a cheap, parallel, these structures is still open. Nanowire lithography (NWL) consists in using nanowires (NWs) as etch masks to transfer SiNWs morphology is transferred onto a graphene flake by a low-power O2 plasma in a deep-reactive-ion-etcher. The to the overlaying NW lateral dimensions. The diameter can be further reduced by multiple O2 etching steps. Field-effect measurements show the transition to a semiconductor for low eim 1 Introduction Graphene is the latest carbon allo-zigzag regions [25–28]. If a GNR is uniquely limited by one issues. Recently, dielectrophoretic assembly was suggested as a means to achieve high-density arrays of individual graphene and GNRs devices from solution [37]. Unzippin
