Innovation Details
 

Detailed Description

This technology is a diamond triode for micro and power electronics. Diamond microtip field emitters are used in triode vacuum electronic devices, sensors and displays. Diamond triode devices having integral anode and grid structures are fabricated using a patented process. Ultra-sharp tips are formed on the emitters in the fabrication process in which diamond is deposited into mold cavities in a two-step deposition sequence. During deposition of the diamond, the carbon graphite content is carefully controlled to enhance emission performance. The tips or the emitters are treated by post-fabrication processes to further enhance performance.
