Characterization of the growth and emission properties of hybrid carbon films contatining carbon nanotubes

摘要

We report our recent progress in the synthesis and characterization of hybrid carbon films produced by microwave plamsa-enhanced chemical vapor deposition. Hybrid carbon films contain multiple allortopes of carbon in the same film by design, i.e. diamond plus carbon nanotubes. Such films may be of particular interest for appliations in field emission displays. A current research issue is field-induced emission emchanisms is the possible role which local field enhancement for sharp geometrical structures plays in electron emission versus the role of the electronic states at an sp~2/sp~3 interface. In these experiments, we investigate this issue in the context of the observed growth morphologies.
