Outline of Final Research Achievements

In this study, research was carried out on the development of single-photon sources using carbon nanotubes and graphene as optical and electronic devices, and on the development of silicon photonics devices using CNTs and graphene. Here, we have successfully observed emission from carbon nanotubes with controlled cross-linked structures and molecular modifications of carbon nanotubes. In addition, the development of evanescent optical coupling technology between carbon nanotubes and silicon photonics was promoted, and the coupling technology between carbon nanotubes and silicon photonics was successfully constructed. Furthermore, we succeeded in developing a novel method for creating superconducting devices using carbon nanotubes as templates and in constructing a device fabrication technique.
