| Outline of Final Research Achievements |
As an ultimate low-dimensional material utilizing a nanospace, ionic atomic chains in which two different elements stably align alternately inside a carbon nanotube have been successful synthesized. Our experiments and theoretical studies indicate that the one-dimensional ionic crystals have distinctive physical properties from those of their bulk structures and that the properties can be modified by introducing only a single atomic defect into the chains. In this study, we have also developed a technique to detect single light atoms such as lithium, fluorine, sodium and chlorine trapped in a nanospace by means of electron energy loss spectroscopy. Then, we have also tried to measure the physical properties of one-dimenisional structures. The high-resolution electron energy-loss spectroscopy combined with high-resolution transmission electron microscopy has unambiguously examined the localized electronic properties at defects in a single carbon nanotube.
