碳钛颗粒膜表面电子发射特性
Electron Emission Characteristics of C-Ti Granular Films
摘要
Abstract
C-Ti granular films deposited by magnetron sputtering were taken as material of surface-conduction e-lectron emitter for SED(surface-conduction electron-emission display). In the effect of increasing triangular wave voltage, the device voltage amplitude was below 17V, volt-ampere characteristics showed a linear, the corresponding film surface hadn't change; Further increase in device voltage amplitude, volt-ampere characteristics showed a negative resistance characteristics, while the surface electron emission could be observed. The film surface of maximum of surface electron emission current reached to 7. 2 jxA and the emission efficiency reached to 0. 094 3 % , and the film appeared pale and produced significant pore structure. According to F-N theory, fitting the device voltage and emission current, the result appears linear which indicated that electron emission from field emission.关键词
