Abstract
An electron emission cathode includes: an n-type semiconductor film including diamond particles partially projecting from a surface of the n-type semiconductor film; and an anode opposing the n-type semiconductor film with a vacuum interposed therebetween. Electrons are emitted by applying a voltage between the anode and the n-type semiconductor film.
