Electron-emitting element, method of making the same, and electronic device |
摘要 |
An electron-emitting element comprises a diamond substrate, and a diamond protrusion grown on a surface of the diamond substrate so as to have a pointed portion in a form capable of emitting an electron. Since the diamond protrusion formed by growth has a sharply pointed tip portion, it can fully emit electrons. Preferably, the surface of the diamond substrate is a {100} face, and the diamond protrusion is surrounded by {111} faces.
