Multiwalled Nanotubes - Tip Growth
Thermal Chemical Vapor Deposition: The growth species
is generated by dissociative adsorption of hydrocarbon on catalyst surface.
Nanotubes are formed via the Vapor-Liquid-Solid (VLS) mechanism.
- Substrate with catalyst thin film
- Substrate pretreatment induces formation of nanoparticle catalyst
- Catalyst surface melting on a high temperature substrate. We propose
a solid core model.
