Abstract
Embodiments of the present invention provide methods for the fabrication of carbon nanotubes using composite metal films. A composite metal film is fabricated to provide uniform catalytic sites to facilitate the uniform growth of carbon nanotubes. Further embodiments provide embedded nanoparticles for carbon nanotube fabrication. Embodiments of the invention are capable of maintaining the integrity of the catalytic sites at temperatures used in carbon nanotube fabrication processes, 600 to 1100° C.
