Outline of Final Research Achievements

In this study, we established novel microfabrication technique and low dimensional crystal growth technique by using templates of nanocarbon materials, and we fabricated one-dimensional nanowires with ~ 10-nm thickness. We fabricated NbN superconducting nanowires. We observed size effects of superconductors, such as quantum phase slip and thermal phase slip, and we found their mechanisms by using very thin nanowires. We also grew aluminum-oxide nanowires on carbon nanotube templates, and observed the change of photoluminescence spectra by their growth.
