ELECTRONIC EMITTER AND ITS FORMATION PROCESS OPTIONS Russian patent published in 1997 - IPC

FIELD: electronic devices with autoelectronic emission. SUBSTANCE: electron emitter has diamond coating applied to surface of selectively shaped conducting semiconducting material. Its manufacturing process includes stage during which carbon ions are implanted in conducting semiconducting material surface so as to make them function as nucleation areas for diamond growing. As an alternative, conducting layer may be applied to diamond coating and conducting semiconducting removed to form diamond-coated electron emitter. EFFECT: facilitated manufacture of electron emitter. 17 cl, 29 dwg
