FIELD: electronic engineering; light sources, plasma displays, cathode-ray tubes. SUBSTANCE: autoemission cathode is manufactured from at least one body containing first substance. Procedures include organizing roughness on emitting body surface, adding ions of second substance having low work function to emitting surface of body, and modifying emitting surface by exciting autoemission when applying variable electric field. EFFECT: reduced work function, , improved service life and environmental friendliness, reduced cost of cathode and autoemission device. 20 cl, 6 dwg
