A METHOD FOR MANUFACTURING CARBON NANOTUBES FOR FIELD EMISSION DEVICES AND CARBON NANOTUBES FOR FIELD EMISSION DEVICE OBTAINED FROM THIS METHOD

摘要

A method for manufacturing carbon nanotubes for field emission devices and carbon nanotubes for field emission device obtained from this method are provided to simplify the manufacturing process by adhering the carbon nanotube on the substrate by using an arc discharging. The arc discharging is performed on a substrate in an arc discharge chamber. The carbon nanotube is arranged on the substrate by the arc discharging. Here, impurities of the carbon nanotube are strongly combined to the wall and end part. The substrate is processed in an organic solvent and the carbon nanotube is horizontally arranged. The substrate is heat-treated, the organic solvent is removed and the impurity is exposed. The carbon nanotube is perpendicularly arranged on the substrate.
