Outline of Final Research Achievements

We proposed a novel method for preparing semiconducting single-walled carbon nanotube (SWCNT) arrays by selectively eliminating the full length of metallic SWCNTs grown on substrates. Isotope labeling study unveiled growth process of individual SWCNTs, which is beneficial for growing long and high-density SWCNT arrays. Coaxial hetero nanotubes composed of SWCNTs and boron nitride nanotube were realized toward all-nanotube transistors.

Academic Significance and Societal Importance of the Research Achievements

本成果により大面積に半導体CNT配向構造を得る道筋が開かれたことから，CNTを用いた電界効果トランジスタなどの工業的応用の実現が期待される．また，従来分析不可能であった単一単層CNTの成長過程を追跡が可能となり，成長メカニズムの理解による単層CNT構造制御合成に近付いた．単層CNTと異種ナノチューブの複合構造の実現は，2次元物質で盛んなヘテロ構造の研究を1次元物質へと広げるものであり，オールナノチューブトランジスタを始めとする様々な新奇構造デバイスの実現が期待される．
