Interaction of Carbon Nanotubes and Diamonds Under Hot-Filament Chemical Vapor Deposition Conditions

SEM and Raman analysis of the early stage nucleation are used to develop a hypothesis of diamond nucleation enhancement by CNT under HFCVD conditions. It is found that the nucleation takes places by etching of the CNT to create a new carbonaceous surface, onto which diamond nucleates. This mechanism is different from the present understanding of the diamond nucleation enhancement by CNTs.
