| Research Abstract |
Novel carbon nanotube (CNT) hybrid materials have been successfully fabricated, which include metal-nanowire encapsulating CNT and graphene nanoribbon (GNR) encapsulating CNT. By using high-resolution transmission electron microscopy (TEM), we were able to observed individual metal atoms aligned within the CNTs, where the metal atoms oftentimes exhibit helical alignment in the nanotubes. By using a specially developed separation technique of metal-semiconductior CNTs, we can obtain very pure (>99%) semiconducting CNT. The thin-film transistors (TFT) with these pure semiconducting CNTs, we have been successful in achieving very high mobility together with high on/off ratios in the transistor performance. These achievement have been widely reported by the Japanese mass media, which include Asahi, Yomiuri, Mainichi, Nikkei and Chunichi newspapers.
