Abstract:
1. A method for synthesizing a single-wall carbon nanotube array, comprising the steps of: receiving a catalyst thin film formed on a surface of a substrate into a chemical vapor deposition reactor; selectively heating the catalyst thin film up to a predetermined temperature; vaporizing a graphite block to introduce gaseous carbon into the chemical vapor deposition reactor; introducing a reactant gas containing a carbon source gas selected from the group consisting of methane, ethylene, acetylene, and mixtures thereof, into the chemical vapor deposition reactor, wherein the carbon source gas and the gaseous carbon reach the catalyst thin film to form the single-wall carbon nanotube array comprising a plurality of aligned single-wall carbon nanotubes originating and extending outwardly from the surface of the substrate, the carbon source gas and the gaseous carbon act as sources for carbon in the carbon nanotubes.
