In this study, a nondestructive method to mass produce crossed nanotube-graphene junctions through twice polymer-mediated transfer techniques and selective oxygen plasma etching was developed. Raman and conductance measurements demonstrate that the quality and electrical properties of the single-layer graphene (SLG) sheets are uniform over a large area. Furthermore, SLG synthesis and device fabrication discussed here also provide a reproducible method to pattern graphene sheet arrays for making graphene-based microdevices over large areas and with high yield, which is compatible with standard thin film technologies and allows SLG to be integrated into large scale electronics circuitry within several simple steps that can be easily streamlined and automated. These results might offer grounds for the creation of a wide variety of molecular rectifiers and other functional nano/molecular devices.
