Abstract (en)
[origin: WO2008074825A1] The invention relates to a cathode structure of the triode type, comprising, superposed on a support (41), a cathode electrode (42), an electrical insulation layer (44) and a gate electrode (45), the electrical insulation layer (44) and the gate electrode (45) having emission openings (46) revealing at least one electron-emitting element (48) electrically connected to the cathode electrode (42), the structure further including a refocusing electrode placed so as to refocus the electrons extracted by the gate electrode (45). The refocusing electrode (50) is placed on said electrical insulation layer (44) and is connected to electrical connection means for applying a refocusing voltage to it via electrically conducting nanotubes (58). The invention also relates to a matrix-controlled field-emission device.
