In a method of manufacturing a field emitter, a patterned conductive layer is formed on a substrate, an upper surface of the conductive layer is coated with a mixture of a field emission material and metal powder, the mixture is thermally treated to improve adhesion of the mixture to the conductive layer, and a field emission material and a metal deposited on a portion of the substrate other than the conductive layer are removed. Accordingly, the lifespan and field emission characteristic of the field emitter are greatly improved, and a large area field emitter having excellent characteristics that cannot be realized in the conventional art is fabricated.

Method of manufacturing field emitter

An electron amplifier and a method of manufacturing the same are provided. The electron amplifier includes a substrate in which a plurality of through holes are formed, a resistive layer deposited on the sidewalls of the through holes, an electron emissive layer including carbon nanotubes which is deposited on the resistive layer, and an electrode layer formed on each of the upper and lower sides of the substrate. Because the electron emissive layer of the electron amplifier is uniform and provides a high electron emission efficiency, the electron amplification efficiency is improved. The electron amplifier manufacturing method enables economical mass production of electron amplifiers.

Electron amplifier utilizing carbon nanotubes and method of manufacturing the same

A field emitter device including carbon nanotubes each of which has a protective membrane is provided. The protective membrane is formed of a nitride, a carbide, or an oxide. Suitable nitrides for the protective membrane include boron nitride, aluminum nitride, boron carbon nitride, and gallium nitride. The protective membrane protects the carbon nanotubes from damage due to arcing or an unnecessary remaining gas and thus improves field emission characteristics and stability of the field emitter device.
