We report on the fabrication of field emission devices with integrated focusing electrodes that use dense films of multiwalled carbon nanotubes for the emitter material. The fabrication process used to realize these devices is completely compatible with large-scale integrated device production techniques. The current vs. voltage characteristics of these devices were examined and displayed a low turn-on voltage for initiation of electron emission. The effects of the focusing electrode on the field emission characteristics were explored along with the gain, frequency response, and output impedance of these devices. Details on the fabrication process and aspects of device performance will be discussed.
