Abstract
A charge dissipation field emission device (200, 300, 400) includes a supporting substrate (210, 310, 410), a cathode (215, 315, 415) formed thereon, a dielectric layer (240, 340, 440) formed on the cathode (215, 315, 415) and having emitter wells (260, 360, 460) and a charge dissipation well (252, 352, 452, 453) exposing a charge-collecting surface (248, 348, 448, 449), for bleeding off gaseous positive charge generated during the operation of the charge dissipation field emission device (200, 300, 400), an electron emitter (270, 370, 470) formed in each of the emitter wells (260, 360, 460), and an anode (280, 380, 480) spaced from the dielectric layer (240, 340, 440) for collecting electrons emitted by the electron emitters (270, 370, 470).
