    Abstract: A method of reducing electronic work function, reducing threshold field emission values, converting semiconducting behavior to metallic behavior, increasing the electron density state at the Fermi level, and increasing electron emission site density, of nanostructure or nanotube-containing material, the method including: forming openings in the nanotube-containing material; introducing a foreign species such as an alkali metal into at least some of the openings; and closing the openings, thereby forming capsules filled with the foreign species, and forming field emission cathode and flat panel displays using these capsules.

    Abstract: An electron-emitting device including a protective layer that is formed on a catalyst layer to protect the catalyst layer from the deleterious environmental conditions before or during a cathode process. The present invention further includes a half etching process that is adapted to partially remove portions of the protective layer from the catalyst layer to etch the catalyst layer except carbon nano-tube growing portions. Portions of the protective layer still remain on the catalyst layer to protect the catalyst layer from the deleterious conditions from next cathode formation process.

    Abstract: The present invention relates to a field emitter array used in various devices including a nanotube-based display and a microwave-amplifying device. In prior art, an electron accelerated by an electric field collides, for example, with a phosphor on the screen. Light is emitted as a positive ion drops out of the phosphor. Destruction or deformation of the emitter's structure can occur if the positive ion becomes accelerated and collides with the emitter, which results in instability or interruption of the emitter's operation. According to the present invention, coating a carbon nanotube with a very thin semiconductor or insulating material with a high degree of hardness can protect the carbon nanotube from the external particles (particularly, positive ions). The thin layer also provides for easy electron emission under low voltage, thereby greatly improving the uniformity and stability of electron emission.
