Abstract:
A thermal chemical vapor deposition method to vertically align carbon nanotubes on a substrate using hydro-carbon gases, the method comprising:(a) catalytically thermally decomposing the hydro-carbon gases at a temperature no greater than 600Â° C. by passing the hydro-carbon gases through a mesh which is made of Ni, Fe, Co, Y, Pd, Pt, Au or an alloy of two or more of these materials or on which Ni, Fe, Co, Y, Pd, Pt, Au or an alloy of two or more of these materials is deposited; and (b) decomposing catalyticallyâ€”and thermally-decomposed hydro-carbon gases by applying DC voltage to the space between a carbon nanotube growing substrate and an electrode substrate which is made of Ni, Fe, Co, Y, Pd, Pt, Au or an alloy of two or more of these materials or on which Ni, Fe, Co, Y, Pd, Pt, Au or an alloy of two or more of these materials is deposited.
