Model of Tunneling Processes in Composite Nanostructures for Vacuum Field- and Photoemission Devices
A phenomenological model of tunneling of electrons into vacuum from a composite nanostructure - a dielectric film of diamond-like carbon on a molybdenum base - is constructed. Three mechanisms of field emission from the metal-dielectric-vacuum structure are taken into account, assuming continuity of the injection-drift-emission current density. A qualitative correspondence of the character of calculated current characteristics to the result of an experimental study is obtained.
