    摘要: Techniques for increasing conductivity of graphene films by chemical doping are provided. In one aspect, a method for increasing conductivity of a graphene film includes the following steps. The graphene film is formed from one or more graphene sheets. The graphene sheets are exposed to a solution having a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The graphene film can be formed prior to the graphene sheets being exposed to the one-electron oxidant solution. Alternatively, the graphene sheets can be exposed to the one-electron oxidant solution prior to the graphene film being formed. A method of fabricating a transparent electrode on a photovoltaic device from a graphene film is also provided.

    摘要: A method of forming a structure having selectively placed carbon nanotubes, a method of making charged carbon nanotubes, a bi-functional precursor, and a structure having a high density carbon nanotube layer with minimal bundling. Carbon nanotubes are selectively placed on a substrate having two regions. The first region has an isoelectric point exceeding the second region's isoelectric point. The substrate is immersed in a solution of a bi-functional precursor having anchoring and charged ends. The anchoring end bonds to the first region to form a self-assembled monolayer having a charged end. The substrate with charged monolayer is immersed in a solution of carbon nanotubes having an opposite charge to form a carbon nanotube layer on the self-assembled monolayer. The charged carbon nanotubes are made by functionalization or coating with an ionic surfactant.
