Since properties of single-walled carbon nanotubes (SWNTs) depend on their structure, namely chirality, there is a strong demand for a method of obtaining single-chirality SWNTs for various applications. In order to clarify the growth mechanism of SWNTs and achieve the chirality-controlled growth, we demonstrated catalytic CVD method under low temperature and pressure conditions. By reducing the pressure, low temperature growth of single-walled carbon nanotubes were realized. We found that the optimum synthesis temperature decreases as the ethanol vapor pressure decreases. It is demonstrated that the diameter of the nanotubes synthesized at low pressure and temperature tends to be smaller than that at the conventional conditions.
