Abstract
A model accounting for anomalously high field emission of electrons from diamondlike films in a rough vacuum is suggested. This effect is shown to be associated with a positive ion charge forming on the film. The ions arise because of residual gas ionization in the electrode gap. The pressure maximizing the emission current is determined.
