Title
(EN) FIELD EMITTER STRUCTURES
(FR) STRUCTURES EMETTRICES DE CHAMP
Abstract
(EN)
A field emitter device comprises a dielectric anodic aluminium oxide layer having pores filled with wires the front ends of which constitute individual field emitting cathodes, a gate electrode overlying a front surface of the layer, and an address electrode overlying a back surface of the layer and in electrical contact with the wires. The problem of short circuit between the gate electrode and the field emitter is overcome by cleaning the pore walls adjacent the gate electrode and/or by selectively dissolving the back ends of individual wires.
(FR)
Un dispositif émetteur de champ comprend une couche anodique diélectrique d'oxyde d'aluminium dotée de pores remplis de fils dont les extrémités frontales constituent des cathodes séparées émettrices de champ, une électrode de grille recouvrant la surface frontale de cette couche, et une électrode d'adressage recouvrant la surface arrière de cette couche et en contact électrique avec les fils. Le problème du court-circuit entre l'électrode de grille et l'émetteur de champ est résolu grâce au nettoyage des parois de pores adjacentes à l'électrode de grille et/ou par la dissolution sélective des extrémités arrières de chacun des fils.
