Abstract:
1. A method for forming a cleaned nanotube-graphene hybrid film, comprising: depositing nanotube film over a substrate to produce a uniform layer of nanotube film; removing impurities from a surface of the uniform layer of nanotube film not contacting the substrate to produce a cleaned uniform layer of nanotube film, wherein said removing impurities from the surface of the uniform layer of nanotube film comprises: depositing a layer of graphene over the cleaned uniform layer of nanotube film to produce a nanotube-graphene hybrid film; and removing impurities from a surface of the nanotube-graphene hybrid film to produce a cleaned nanotube-graphene hybrid film, wherein the hybrid film has improved electrical performance via decreasing nanotube resistance by increasing contact area through use of graphene as a bridge; repeating the steps of (i) producing a uniform layer of nanotube film, (ii) producing a cleaned layer of nanotube film, (iii) producing a nanotube-graphene hybrid film, and (iv) producing a cleaned nanotube-graphene hybrid film to form a cleaned nanotube-graphene hybrid film of a desired thickness; and chemically doping the cleaned nanotube-graphene hybrid film.
