Use new method to get SWNT

China Peking University cooperate with Chinese Academy of Sciences to use ethanol / methane by chemical vapor deposition method to get  ultrahigh-density semiconductor array level of  single-walled carbon nanotube.

Recently, researchers from Peking University and the Chinese Academy of Sciences reported a ethanol / methane chemical vapor deposition of the scientific method to prepare single-walled carbon nanotube array level. SWNT horizontal array prepared by the method of a semiconductor single-walled carbon nanotube purity of 91% and a density higher than 100 tubes / μm. This method is at a certain temperature, thermal decomposition of ethanol is completely for Trojan-Mo catalyst to provide a carbon atom to generate a high-density single wall carbon nanotubes; and incomplete thermal decomposition of methane is used to provide the free H base metal to prevent the formation of single-walled carbon nanotubes. Ethanol and methane moderate activity, vital high controllability, and the synergistic effect of both high purity and high-density semiconductor single-walled carbon nanotube growth. The study was a large area of high-density single-walled carbon nanotube synthesis horizontal array of a step forward, showing the potential applications of carbon nanotube electronics.
