Outline of Final Research Achievements

The aim of this research project was to develop a new way to utilize abundant sulfur. In this research, we successfully synthesized a one-dimensional conductor of elemental sulfur inside carbon nanotubes. To explore a previously unobserved one-dimensional superconductor, we synthesized a hybridized one-dimensional conductor consisting of metallic sulfur and metallic carbon nanotubes. Although superconductivity has not been confirmed directly up to now, we found a clue for a one-dimensional superconducting mechanism of the sulfur-carbon nanohybrids using Raman spectroscopy.
