| Abstract: | Nanostructured carbon-based materials such as carbon nanotubes,nanodiamond,carbon nanofibers exhibit good field emission properties.They have a low threshold electric field for emission and a high emission current density which make them attractive for potential applications.In this article,the recent research progress on carbon nano-materials field emission properties are reviewed.The emphasis on the technical specifications which have some effects in field emission characteristics are discussed.Some questions to be solved in the future are also mentioned. |
