△ [11p-W621-17] Purity Improvement of (6,4) Single-Walled Carbon Nanotubes by Controlling Gas Phase Condition using Plasma
Keywords:Single-Walled Carbon Nanotubes, Chirality-Controlled, Plasma CVD
We have succeeded in high purity synthesis of (6,4) SWNTs by controlling the surface condition of the nanoscale catalyst. In this study, we focused on correlation between (6,4) SWNT growth and gas phase state during synthesis for further increasing the purity of (6, 4) SWNTs. As a result, it is clarified that correlation was found between the amount of specific precursor and the chirality purity. This indicates that the specific kinds of precursors can contribute to deciding the preferential synthesis of specific chirality SWNTs.
