CRT lighting element with carbon field emitters

摘要

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. (C) 2002 Elsevier Science Ltd. All rights reserved. [References: 6]
