Fabrication and structure of electron emitters coated with material such as carbon |
摘要 |
A cathode structure suitable for a flat panel display is provided with coated emitters. The emitters are formed with material, typically nickel, capable of growing to a high aspect ratio. These emitters are then coated with carbon containing material for improving the chemical robustness and reducing the work function. One coating process is a DC plasma deposition process in which acetylene is pumped through a DC plasma reactor to create a DC plasma for coating the cathode structure. An alternative coating process is to electrically deposit raw carbon-based material onto the surface of the emitters, and subsequently reduce the raw carbon-based material to the carbon containing material. Work function of coated emitters is typically reduced by about 0.8 to 1.0 eV.
