Abstract

Une cathode à émission de champ comprend une couche de matériau conducteur (14) et une pellicule de diamant amorphe (12), jouant le rôle d'un matériau à faible énergie d'extraction, déposée sur le matériau conducteur pour former des sites d'émission. Les sites d'émission contiennent chacun au moins deux sous-zones présentant des affinités électroniques différentes.
