A quantitative theory for the operation of a Spindt-type cold cathode emitter embedded in a thin diamond film doped with substitutional Nitrogen is presented. The device, recently developed by M. W.Geis and colleagues at the MIT Lincoln Laboratory, is characterized by high field emission currents at low power. The theoretical model treats injection, by internal field emission, at the metal-diamond interface, transport through the diamond film and emission at the diamond-vacuum surface. The calculated 1-V characteristics agree well with the experimental results of Geis et al.
