Abstract

In this paper, electron field emission properties of nano-diamond films, which were prepared using either CH₄/H₂/ N₂ or CH₄ /Ar microwave plasma enhanced chemical vapor deposition, were studied. X-ray photoelectron spectroscopy detection indicates that nitrogen was incorporated into the nano-diamond film grown in CH₄/H₂/N₂ mixture. This nano-diamond film shows a very low threshold electric field of 2.2 V/μm and a high emission current density of 720 μA/cm² at applied field of 6.4 V/μm. Nitrogen incorporation, high grain boundary density and sp²-bonded non-diamond components in the films are believed to be responsible for the electron emission enhancement.
