METHOD FOR PREPARING CARBON NANOTUBES FOR FIELD EMISSION DEVICES BY ELECTRODOPOSITION AND CARBON NANOTUBE FOR FIELD EMISSION DEVICES MADE THEREBY

摘要

A method for manufacturing a carbon nano-tube field emission device by using electro-deposition and a carbon nano-tube field emission device manufactured thereby are provided to enhance electrical/mechanical coherence between a carbon nano-tube and a metal electrode by growing a carbon nano-tube/metal composite on a metal electrode. A carbon nano-tube dispersion process is performed to disperse a carbon nano-tube into a metallic electrolyte of an electroplating device. A growing process is performed to couple the carbon nano-tube and metallic particles in order to grow a carbon nano-tube/metal composite on the metal electrode by applying current to a metal electrode and a relative electrode of the electroplating device. A carbon nano-tube forming process is performed to form the carbon nano-tube by etching chemically the carbon nano-tube/metal composite grown on the metal electrode.
