CRT lighting element with carbon field emitters

Field electron emission from carbon fibres has been investigated. Measured current–voltage characteristics followed the Fowler–Nordheim equation. A cathode ray tube lighting element of a triode vacuum tube was manufactured as an application of a carbon fibre emitter by replacing conventional thermio...

Description
Summary:Field electron emission from carbon fibres has been investigated. Measured current–voltage characteristics followed the Fowler–Nordheim equation. A cathode ray tube lighting element of a triode vacuum tube was manufactured as an application of a carbon fibre emitter by replacing conventional thermionic cathodes with carbon field emitters. Stable and intense electron emission, luminosity and long life of the emitters were demonstrated and discussed.
