Abstract: An electron emitter comprises a tapered-shaped emission tip having a base face and an apex opposite the base face, the emission tip consisting essentially of semiconductor material, the semiconductor material being partially doped n-type and partially doped p-type, wherein the base face is doped one of n-type or p-type and the apex is doped opposite type of the base face and a p-n junction is thereby formed at a position between the base face and the apex.
