摘要：

Forest of single-walled carbon nanotubes (SWNTs) was grown at 450 degrees C by water-plasma chemical vapor deposition using ultrathin iron on alumina supporting film. The growth rate of the SWNT forest is similar to 0.9 mu m/min, and the diameters of nanotubes are mainly in a range of 3.0 similar to 3.5 nm. The low intensity ratio of D- to G-band (I-D/I-G similar to 0.098) in Raman spectra indicates that our SWNT forest grown at 450 degrees C is fairly pure and crystalline. This low temperature growth of SWNT forest may enable variable applications requiring the vertically-aligned nanotubes to obtain large surface area.
