Abstract
An electron-emitting device includes an electroconductive member and a lanthanum boride layer on the electroconductive member and further includes an oxide layer between the electroconductive member and the lanthanum boride layer. The oxide layer can contain a lanthanum element. The lanthanum boride layer can be overlaid with a lanthanum oxide layer.
Claims18
An electron-emitting device that includes an electron-emitting member and emits electrons from a surface of the electron-emitting member in an electric field, the electron-emitting member including an electroconductive member and a lanthanum boride layer disposed on the electroconductive member,
- wherein an oxide layer is disposed between the electroconductive member and the lanthanum boride layer, and
- wherein the electroconductive member is formed of molybdenum and the oxide layer contains an oxide of molybdenum and an oxide of lanthanum, or the electroconductive member is formed of tungsten and the oxide layer contains an oxide of tungsten and an oxide of lanthanum.
