Abstract
A field emission device (200, 300, 400, 500) includes a supporting substrate (210, 310, 410, 510), a cathode (215, 315, 415, 515) formed thereon, a plurality of electron emitters (270, 370, 470, 570) and a plurality of gate extraction electrodes (250, 350, 450, 550) proximately disposed to the plurality of electron emitters (270, 370, 470, 570) for effecting electron emission therefrom, a major dielectric surface (248, 348, 448, 548) disposed between the plurality of gate extraction electrodes (250, 350, 450, 550), a charge dissipation layer (252, 352, 452, 552) formed on the major dielectric surface (248, 348, 448, 548), and an anode (280, 380, 480, 580) spaced from the gate extraction electrodes (250, 350, 450, 550).
