Carbon nanotubes on a substrate

摘要: The present invention includes carbon nanotubes whose hollow cores are 100% filled with conductive filler. in uniform arrays on a substrate and well-aligned can be densely packed. uniformity of the nanotube is indicated by length diameter nanotubes, both which vary from to given array no more than about 5%. alignment perpendicular growth substrates achieved part simultaneous filler within core packed nanotubes. provides where each contact at least one nearest-neighbor nanotube. coated catalyst, single crystals carbide formed solid state reaction between material catalyst. further method for making substrates. steps depositing catalyst onto as prepared substrate, creating vacuum vessel contains flowing H2/inert (e.g. Ar) gas increase maintain pressure vessel, increasing temperature changing H2/Ar ethylene such that flows vessel. Additionally, varying density separation particles used control
