Time- and Area-Resolved Investigation of Field-Induced Electron Emission from Nanocarbon Films

This paper investigates electron emission from nanocarbon films. The emitter surface represents a kind of 2d medium with spatial and temporal dispersion, principally suitable for development of oscillations and waves. Detection and characterization of these oscillatory phenomena can give new information on properties, performance and interaction of efficient emission centers. To measure a signal representing emission current density at a selected spatial position, the light flux from the corresponding image spot is collected with an optical fibre probe and then directed to a photomultiplier
