Abstract A stable electron emission was obtained at as low as about 2.5V/μm from acid treated diamond films. The emission data were fitted with Folwer-Nordheim theory. It is found that the non-electrons are emitted from some protrusions on surface of diamond films, and that after acid treatment, the effective work function is lowered, and the emission area is increased to two folds of those of as-grown films. These results were discussed.
