  • Sectioned resistor layer for a carbon nanotube electron-emitting device
    Patent number: 7053538
    Abstract: An electron-emitting device contains an emitter resistor layer patterned into multiple laterally separated sections situated between the electron-emissive elements, on one hand, and emitter electrodes, on the other hand. Sections of the seed layer are spaced apart along each emitter electrode to electrically decouple electron emission elements disposed on the resistor layer.
