Abstract

Effects of Fe catalyst film and carbon nanotube (CNT) growth temperature on the characteristics of carbon nanotube were investigated in thermal chemical vapor deposition (CVD) process. Fe catalyst was prepared by DC magnetron sputter with thickness of 5-40 nm and pre-treated with ammonia gas. CNTs were grown at $700-900^{\circ}C$. It was found that the island formation of catalyst is necessary for the CNT growth. The diameter of these CNTs shows a strong correlation with the catalyst film thickness and growth temperature.
