Outline of Research at the Start

SWCNTs are promising for the next generation energy-efficient transistors. However, there is a fundamental challenge to control the chirality. Here, it is proposed to engineer the chirality of individual SWCNTs, and to investigate the transition mechanism by in situ TEM probing.

Outline of Final Research Achievements

Single-walled carbon nanotubes (SWCNTs) have superior electrical, mechanical, and thermal properties and are promising for the next generation energy-efficient transistors. However, depending on the chirality, 1/3 of the nanotubes are metallic. In this project, a method is developed to transform the chirality and change the metallic nanotubes into semiconductors. By using in situ transmission electron microscopy (TEM) probing technique and applying mechanical tension and high temperature, the local chirality of individual nanotubes was successfully transformed. Metal-to-semiconductor transition was realized by using closed-loop (feedback) control. Nanotransistors with the channel length as short as 2.8 nanometers were fabricated using the chirality-transformed nanotubes as channels and quantum transport was demonstrated at room temperature.

Academic Significance and Societal Importance of the Research Achievements

カーボンナノチューブのカイラリティ（らせん構造）を制御することは、エレクトロニクスへの応用において極めて重要である。本プロジェクトでは、個々のカーボンナノチューブの局所的なカイラリティを変換する手法を開発した。このカイラリティ変換により、金属性カーボンナノチューブは、ナノトランジスタを作製するための半導体へと変化した。この成果は、5ナノメートル以下のナノチューブトランジスタを開発することに貢献する。
