ABSTRACT:
Process for the production of a field effect electron source and source obtained by said process, application to display means by cathodoluminescence.
On an insulating substrate (2), said source comprises at least one cathode conductor (4), an insulating layer (6) covering the latter, at least one grid (8) formed on the insulating layer, holes (10) being formed through said grid and the insulating layer, and microtips (12) made from an electron emitting, metallic material, formed in said holes and covered with a deposit (13) of carbon diamond or diamond like carbon particles formed by electrophoresis or by joint electrochemical deposition of metal and carbon diamond or diamond like carbon.
