Abstract:
1. A method for synthesizing an array of a plurality of carbon nanotubes, each of said carbon nanotubes having a first end attached to a conductive substrate, and a second end extending from said conductive substrate, each of said carbon nanotubes having a closed outer wall defining a core that is hollow, wherein said core is filled more than 10% with a conductive filler, comprising the steps of: (a) depositing a growth catalyst onto said conductive substrate forming a prepared substrate; (b) creating a vacuum within a vessel containing said prepared substrate; (c) flowing H2/Ar gas within said vessel and increasing the pressure within said vessel; (d) increasing the temperature of said prepared substrate; and (e) changing said H2/Ar gas to ethylene gas such that said ethylene gas flows within said vessel.
