Abstract
The autoemission characteristics of carbon films obtained by electric arc sputtering of graphite in a magnetic field were studied. Based on the analysis of the experimental Fowler-Nordheim curves, it was shown that the work function of electrons from the carbon film was ~ 0.2 eV. The current-voltage characteristics were measured at a distance of 10 μm between the carbon film surface and the anode at room temperature.
