CATHODE, ELECTRON GUN, AND CATHODE-RAY TUBE USING FERROELECTRIC EMITTER

摘要

FIELD: electronic engineering. SUBSTANCE: electron gun has substrate, electrode lower layer formed on substrate, cathode layer formed on lower layer of electrode using ferroelectric emitter, upper layer of electrode formed on ferroelectric layer of cathode that has regions capable of emitting electrons from this surface, and electrode exciting layer formed on upper layer of substrate and designed to control electron emission from electron emission region of electrode upper layer. EFFECT: reduced cost and facilitated manufacture of cathode. 9 cl, 10 dwg
