Electron-emitting device, electron source using electron-emitting device, and image forming apparatus |
摘要 |
<p>An electron-emitting device includes a substrate (1), first and second carbon films (10) disposed so as to have a first gap (7) between the first and second carbon films on a surface of the substrate, and first and second electrodes (3,4) electrically connected with the first and the second carbon films respectively, wherein the carbon film has a region showing orientation, and a direction of the orientation is in an approximately parallel direction along the substrate surface. Thereby, it is possible to improve thermal and chemical stability of a carbon film and stabilize good electron emission characteristics over a long period. <IMAGE></p> |
