Development of preparation technique of large-area dual-gate-structure vacuum electron source arrays using CuO nanowire emitters

Field emission display is a competitive technology for next generation flat-panel displays. Self-assembled nanomaterial cold cathodes are easier to fabricate than Spindt-type tip arrays and therefore low cost fabrication on large area could be achieved [1]. In this study, dual-gate-structure vacuum electron source arrays using CuO nanowire field emitters were fabricated and their potential application in field emission display has been explored.
