Research Overview

A variety of carbon-assembled materials, e.g., spherical carbon clusters (fullerenes) such as C60 molecule with its soccer-ball structure, and single-walled carbon nanotubes which have the structure of a rolled-up graphite monolayer, can each be regarded as a carbon-nanostructure that has its own unique physical and chemical properties. The main aims of our research are to make these materials, and also to purify them in our own laboratory, in order to investigate how their individual geometrical structures are reflected in their physical and chemical properties (electronic states, vibrational states,solid-state properties, etc.), and also to study the formation process itself, by examining fabrication conditions.
An arc-burning system, a high-temperature laser-vaporization system, and an alcohol CVD apparatus are currently available as experimental equipment for making fullerenes and single-walled carbon nanotubes. We investigated the single-walled carbon nanotubes obtained by using the arc-burning method, and we dispersed these carbon nanotubes in a surfactant solution. We investigated chirality distributions of individual nanotubes with semi-conductive electronic character, by measuring fluorescence-mapping spectra.
From 2009, a laser-Raman apparatus is available in our laboratory, and Raman spectra were obtained with both soot and solution containing single-walled carbon nanotubes.
Our next goal, is to separate and purify those single-walled carbon nanotubes that have a metallic and semi-conductive character. In addition, we also plan to fabricate single-walled carbon-nanotubes using porous glass and the CVD technique.
