Abstract: In an apparatus and method of generating a carbon nanotube (CNT), a process chamber is heated to a target temperature and a catalyst powder is supplied into the heated process chamber. The catalyst powder moves in a first direction in the process chamber. A source gas is supplied into the process chamber in a second direction opposite to the first direction, so that the source gas delays the movement of the catalyst powder in the first direction and is reacted with the catalyst powder in the process chamber to thereby produce the CNT in the process chamber. Accordingly, the flow of the source gas against the flow of the catalyst powder reduces the drop velocity of the catalyst powder. Therefore, the source gas and the catalyst powder may be reacted with each other for a sufficiently long time.

Abstract: Apparatus and method for compounding carbon nanotubes are provided to uniformly supply a source gas used to compound carbon nanotubes, efficiently exhaust the source gas, and increase a retrieve rate of the carbon nanotubes. According to the apparatus and method, carbon nanotubes are massively compounded.

Abstract: An emitter for a field emission device (FED) designed to increase durability by interposing an ultraviolet (UV) transmissive resistive layer between a substrate and an emitter and a method for fabricating the same. The method includes depositing a transparent electrode on a transparent substrate, forming a resistive layer by stacking an ultraviolet (UV) transmissive resistive material on the transparent electrode, forming an emitter layer by stacking a carbon nanotube (CNT) on the UV transmissive resistive material, and patterning the emitter layer according to a predetermined emitter pattern.
