CVD Synthesis of Single-Walled Carbon Nanotubes from Gold Nanoparticle Catalysts

摘要

The growth of SWNTs using gold nanoparticle catalysts was successfully demonstrated. Investigations are currently underway to achieve low-temperature SWNT growth. Furthermore, a detailed analysis with resonant Raman spectroscopy17 will be carried out to elucidate the metallic to semiconducting ratio of the SWNTs. Given the increased interatomic distance of Au over Fe, Co, or Ni, it is possible that the chirality distribution of SWNTs grown from the Au nanoparticles could be different from those of conventional catalysts. Our successful synthesis opens up the route for the investigation of chirality modification through parameter control during the CVD.
