Claim:
1. An electrically conductive carbon nanostructure device comprising a single carbon nanotube disposed on a planar substrate, an ˜2 nm thick nickel catalized electrically conductive amorphous carbon-containing interfacial layer disposed on said single carbon nanotube, wherein said single carbon nanotube is fully wrapped by said ˜2 nm thick nickel catalized electrically conductive amorphous carbon-containing interfacial layer, and a metal electrode disposed on top of said ˜2 nm thick nickel catalized electrically conductive amorphous carbon-containing interfacial layer and on top of said planar substrate, wherein said ˜2 nm thick nickel catalized electrically conductive amorphous carbon-containing interfacial layer is in a graphitized state, wherein said ˜2 nm thick nickel catalized carbon-containing interfacial layer in a graphitized state comprises a covalent chemical bond to said single carbon nanotube having an enhanced electrical contact area relative to a non-graphitized electrically conductive interfacial layer, wherein said covalent bonding between said single carbon nanotube and said ˜2 nm thick nickel catalized electrically conductive amorphous carbon-containing interfacial layer in a graphitized state comprises a sp 2 bonding that is similar to a sp 2 bonding of said the carbon nanotube forming an extended effective wave function overlap for electrical conduction band electrons in the form of P z -P z covalent bonding, wherein said ˜2 nm thick nickel catalized electrically conductive amorphous electrically conductive carbon-containing interfacial layer in a graphitized state is configured to enhance electrical conductivity between said single carbon nanotube and said metal electrode.
