ABSTRACT:
The present invention relates to an electron emitting device having a structure for efficiently emitting electrons. The electron emitting device has a substrate comprised of an n-type diamond, and a pointed projection provided on the substrate. The projection comprises a base provided on the substrate side, and an electron emission portion provided on the base and emitting electrons from the tip thereof. The base is comprised of an n-type diamond. The electron emission portion is comprised of a p-type diamond. The length from the tip of the projection (electron emission portion) to the interface between the base and the electron emission portion is preferably 100 nm or less.
