Title:
COLD CATHODES MADE OF CARBON MATERIALS
Document Type and Number:
WIPO Patent Application WO/2005/006378
Kind Code:
A1
Abstract:
The invention relates to electronic engineering, in particular to producing autoemission cathodes which are used in the form of an electrode source for different-purpose electrovacuum devices. The use of different materials for producing cold cathodes is one of investigation directions with respect of the use of different materials, including a hydrocarbon material based on a linear-chaining sp1-carbon. Said hydrocarbon material can be embodied in the form of carbon fibres or carbon film based on a linear-chaining sp1-carbon, including films produced by applying a carbon-powder suspension to a substrate. Said substrate can be made of a flexible material. In addition, the cathode can be made of a carbon film obtainable by the deposition thereof from carbon plasma. The inventive method for producing carbon fibres consists in carrying out the reaction of dehydrohalogenation of polymeric fibres from polyvinylidene-halogenides or polyvinyl-halogenides associated with successive heat treatment at a temperature ranging from 400 to 900 °C in vacuum in the order of 10 4Pa. The use of the inventive cold cathodes makes it possible to produce electronic devices and light sources.
