Abstract CNx thin films were prepared using low pressure plasma enhanced chemical vapor deposition (LP-PECVD), and then bombarded by low energy N+2. The compositions before and after N+2 bombardment were compared by using x-ray photoelectron spectroscopy. The electron field emission characteristics of CNx thin films before and after N+2 bombardment were studied under the pressure of 10-6Pa. For the samples, the turn-on emission field decreased from 2.5V/μm to 1.2V/μm while the stable current density increased from 0.5mA/cm2 to a value larger than 1mA/cm2 before and after the bombardment. Our results illustrated that the field emission characteristics were improved after the bombardment of N+2.
