摘要： A method for fabricating a triode field emitter array using carbon nanotubes having excellent electron emission characteristics is provided. In the method for fabricating a triode-structure carbon nanotube field emitter array, a catalyst layer is formed on a cathode electrode without forming a base layer, and carbon nanotubes are grown on the catalyst layer using a Spind't process. In this method, a non-reactive layer is formed on a catalyst layer outside the micro-cavity such that the carbon nanotubes can be grown only on the catalyst within the micro-cavity. Accordingly, even through a separation layer is etched and removed, since carbon nanotubes do not exist outside the micro-cavity, it does not happen that carbon nanotubes are drifted into the micro-cavities. Therefore, the fabrication yield is increased, and the fabrication cost is decreased.

摘要： A field emission device (FED) and a method for fabricating the FED are provided. The FED includes micro-tips with nano-sized surface features, and a focus gate electrode over a gate electrode, wherein one or more gates of the gate electrode is exposed through a single opening of the focus gate electrode. In the FED, occurrence of arcing is suppressed. Although an arcing occurs in the FED, damage of a cathode and a resistor layer is prevented, so that a higher working voltage can be applied to the anode. Also, due to the micro-tips with nano-sized surface features, the emission current density of the FED increases, so that a high-brightness display can be achieved with the FED. The gate turn-on voltage can be lowered due to the micro-tip as a collection of nano-sized tips, thereby reducing power consumption.
