CARBON NANO-TUBE STRUCTURE, METHOD FOR PREPARING CARBON NANO-TUBE, ELECTRIC FUNCTION DEVICE, FINE CATALYST PARTICLE FOR GROWING CARBON NANO-TUBE

摘要

A method for preparing a carbon nano-tube, which comprises (a) a step of depositing fine catalyst particles containing any of Fe-Al, Zr-Co and Hf-Co on a substrate, and (b) a step of growing carbon nano-tubes on the substrate having fine catalyst particles deposited thereon.
