Field emission enhancement of amorphous carbon nitride films by the addition of argon to the reactive gas of nitrogen

In this paper, the addition of argon to the reactive gas of nitrogen caused the increase of the content and size of sp/sup 2/-bonded clusters. This caused the domination of the local connectivity and lowered the surface tunnel barrier. Because of this, the field emission of amorphous carbon nitride (a-CN/sub x/) films was effectively enhanced.
