Electron field emission from room temperature grown carbon nanofibers

The field induced emission from room temperature grown carbon nanofibers at low macroscopic electric field was discussed. It was found that the nanofiber were deposited using methane as a source gas in a conventional rf plasma enhanced chemical vapor deposition reactor. It was observed that nanofibers possessed an average diameter of 300 nm. Analysis shows that the mechanism for emission at low fields was attributed to field enhancement at the tips
