Abstract:

We investigated the effects of catalyst (Fe)/buffer layer (Al2O3) on the vertical growth multiwalled carbon nanotubes (CNTs) synthesized by thermal chemical vapor deposition. The Fe was deposited onto Al2O3/SiO2/Si wafer by using e-beam evaporator. Ethylene was used as a feeding gas while argon was used as a carrier gas. Hydrogen was also introduced. The catalyst layers were optimized to control the length, diameter, purity, and alignment of CNTs. For the optimized conditions we produced vertically aligned CNTs of about 1 cm in length during 10 h. The effects of catalysts on nanotube characteristics were systematically analyzed using SEM, TEM, and Raman measurement.
