Abstract:
A field emitter cell includes a thin film edge emitter normal to a gate layer. The field emitter is a multilayer structure including a low work function material sandwiched between two protective layers. The field emitter may be fabricated from a composite starting structure including a conductive substrate layer, an insulation layer, a standoff layer and a gate layer, with a perforation extending from the gate layer into the substrate layer. The emitter material is conformally deposited by chemical beam deposition along the sidewalls of the perforation. Alternatively, the starting material may be a conductive substrate having a protrusion thereon. The emitter layer, standoff layer, insulation layer, and gate layer are sequentially deposited, and the unwanted portions of each are preferentially removed to provide the desired structure.

Abstract:
A cold cathode electron emission structure includes an amorphous carbon matrix having cesium dispersed therein, with the cesium present in substantially non-crystalline form. A cesium-carbon-oxide layer is positioned on the amorphous carbon matrix, constitutes an electron emission surface and causes the cold cathode electron emission structure to exhibit a lowered surface work function. A display structure including the aforedescribed cold cathode electron emission structure further includes a target electrode including a phosphor and exhibiting a target potential for attraction of electrons. A gate electrode is positioned between the electron emission structure and the target electrode and is biased at a gate potential which attracts electrons, but which is insufficient, in combination with the target potential, to cause emission of a beam of electrons from the electron emission structure. A control electrode is coupled to the electron emission structure and selectively applies a low-voltage control potential which, in combination with the gate potential and the target voltage, is sufficient to cause the electron emission structure to emit a beam of electrons towards the target electrode. The cesium-carbon-oxide layer in combination with the control electrode further enables the achievement of a long focal length, field effect display structure.

Abstract:
The present invention pertains to the use of quasione-dimensional transition metal ternary compounds M X H y Ha Z (where M is a transition metal Mo, W, Ta, Nb; H is sulfur (S), selenium (Se), tellurium (Te); Ha is iodine (I)) and of doped quasi-one-dimensional transition metal ternary compounds M X H y Ha Z , (where M=Ta, Ti, Nb; H is sulfur (S), selenium (Se), tellurium (Te); Ha is iodine (I)) with elements of group lb (silver (Ag), gold (Au), or copper (Cu)) as electron emitters under the influence of an external electric field. The percentage of quasi-onedimensional transition metal ternary compounds and/or doped quasi-one-dimensional transition metal ternary compounds doped with elements of group lb in the active material ranges from 0.01 to 99.9 the rest consisting of additives in the form of conducting, non-conducting or semi-conducting compounds or composites. Electron emission takes place at a pressure below 1 mbar.
