Abstract 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 d
