摘要:
Diamond microtip field emitters (25) are fabricated for use in diode and triode vacuum microelectronic devices, sensors and displays. Ultra-sharp emitter tips are formed in a fabrication process in which diamond is deposited into mold cavities in a two step deposition sequence. During deposition of the diamond, the graphite content is carefully controlled to enhance emission performance. The tips or the emitters (25) may be treated by post fabrication processes, such as sharpening or doping with gold.
