Abstract (en)
The electron source has an isolating substrate (2) with a cathode conductor (4) formed on its upper surface. An isolating layer (6) with an upper grid surface (8) is formed above the cathode conductor. Holes (10) are formed in the upper grid and isolating layer, and diamond like powder grain heaps (12) are formed on the cathode surface in the gaps.
Abstract (fr)
Cette source comprend, sur un substrat isolant (2), au moins un conducteur cathodique (4), une couche isolante (6) qui recouvre celui-ci, au moins une grille (8) formée sur la couche isolante, des trous (10) étant formés à travers cette grille et la couche isolante, et des micro-amas (12) contenant des particules de carbone diamant ou de type diamant qui sont formés dans ces trous par électrophorèse par exemple. <IMAGE>
