ELECTRON EMISSION ELEMENT AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electron emission element having a small potential drop and electron emission of a lower threshold value and a method of manufacturing the same. SOLUTION: At outer periphery of an emitter of which a sharpened tip consists of carbonaceous electron emission substance such as diamond 16 or the like of convex shape 19, a thin conductive layer 15 is installed to expose the tip of the emitter.
