- 論文の詳細を見る
Multiwalled carbon nanotube (MWNT) films were grown on nickel-coated SiO2/Si substrates by atmospheric pressure chemical vapor deposition (CVD) using ethanol and nitrogen as a source material and a carrier gas, respectively. It is revealed that the In2O3:Sn (ITO)-coated glass placed in the reaction zone contributes to the enhancement of the carbon yield, the reduction of carbonaceous particles and the growth direction change of MWNTs. These effects are related to the suppression of the coalescence among the catalytic particles and the vaporization of the volatile compounds formed by the additional In, Sn and O elements evaporated from the ITO film.
