Outline of Final Research Achievements

We have developed the growth techniques of vertically-aligned and horizontally-aligned single-walled carbon nanotubes (SWNTs), and synthesized aligned SWNTs and various polymer composites. We succeeded in controlling the density and length of horizontally-aligned SWNTs and investigated the growth mechanism of SWNTs. Utilizing the interaction between polymers and SWNTs, Joule-heating and electrical breakdown of SWNTs, the selectively-removal of metallic or semi-conducting SWNTs was performed. By using these techniques, field-effect SWNT-transistors were also fabricated.
