Spindt阴极可靠性物理问题
The Physics of the Reliability for Spindt Cathode
摘要
Abstract
The reliability improvement for Spindt cathode are discussed in this paper.The Schotteky diodes in Spindt cathodes are the sources for flashover along oxide walls in cathode cavities.Therefore,move the Schotteky diodes out of Spindt cathodes will improve the Spindt cathodes reliability.The Gray and Green molding process method can be used to make micro-tip array cathode on the metal substrate.Our and other group experiments show that high emission current could be obtained from this cathode and its life time also can be prolonged.关键词
