CARBON NANO-TUBE COMBINED CONTAINING RUTHENIUM NANO-PARTICLES WITH IMPROVED ELECTRIC FIELD EMISSION PROPERTY AND A METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: Carbon nano-tube and a method for manufacturing the same are provided to increase the state density of electrons around Fermi level and lower a work function by combining ruthenium nano-particles with the wall of the carbon nano-tube.;CONSTITUTION: A method for manufacturing carbon nano-tube includes the following: Ruthenium dioxide powder is deposited on carbon nano-tube. The deposited ruthenium dioxide powder is reduced to form ruthenium nano-particles. The carbon nano-tube is directly grown on a substrate on which a buffer layer and a seed layer are formed. The buffer layer is formed based on one selected from a group including SiO_2, Al_2O_3, and MgO. The seed layer is formed based on one metal selected from a group including nickel, iron, and cobalt.;COPYRIGHT KIPO 2011
