Abstract: An electron beam window 20 is formed with six diamond panes 21 to transmit an electron beam 15. The panes 21 are formed in a cylindrical disc 17 of single crystal or of polycrystalline diamond such that each pane 21 is surrounded by a thicker integral peripheral rim 22 which conducts heat away from the panes 21. A heat sink ring 35 can be fitted to the outer cylindrical surface of the peripheral rim 22. A scanning means 36 indexes the electron beam 15 sequentially through each pane 21. The use of diamond panes reduces the electron beam energy converted to heat in each pane 21, the thicker peripheral rim 22 increases cooling of the panes 21, and the scanning movement 37 reduces the temperature rise of the panes 21.

Abstract: A field emission device having emitter tips and a support layer for a gate electrode is provided. Openings in the support layer and the gate layer are sized to provide mechanical support for the gate electrode. Cavities may be formed and mechanically supported by walls between cavities or columns within a cavity. Dielectric layers having openings of different sizes between the emission tips and the gate electrode can decrease leakage current between emitter tips and the gate layer. The emitter tips may comprise a carbon-based material. The device can be formed using processing operations similar to those used in conventional semiconductor device manufacturing.

Abstract: An electron emission device includes a pair of anode and cathode substrates facing each other, and cathode electrodes, an insulating layer, and gate electrodes sequentially deposited on the cathode substrate. Gate holes are formed within the respective pixels by partially removing the gate electrodes and the insulating layer. Each pixel is divided into a central pixel region and a peripheral pixel region. Electron emission regions are placed on the cathode electrodes inside the gate holes to emit electrons. Anode electrodes and a phosphor screen are formed on the anode substrate. A uniform electric field is applied to the electron emission regions arranged at the central pixel region, and a non-uniform electric field is applied to the electron emission regions arranged at the peripheral pixel region excluding the central pixel region.
