摘要:
According to the embodiment, an electron emission element includes a conductive substrate, a first diamond layer of a first conductivity type formed on the conductive substrate, and a second diamond layer of the first conductivity type formed on the first diamond layer. Thereby, it becomes possible to provide the electron emission element having a high electron emission amount and a high current density even in a low electric field at low temperature and the electron emission apparatus using this electron emission element.
