Outline of Final Research Achievements

We have developed a chemical vapor deposition (CVD) method named ‘submarine-style substrate heating CVD method’, where the deposition is enabled in the environment of a high temperature gradient under the liquid level, and succeeded to synthesize as-grown free-standing carbon nanoribbon. Moreover, we have set up a hand-made mapping measurement system of Raman spectra and revealed that the carbon nanoribbon is made of graphene sheets. However, we could not clarify its electric property as it was difficult to improve its purity. On the other hand, we have succeeded to create a novel carbon nanomaterial using the submarine-style CVD method and named the material ‘carbon nanopot’. Carbon nanopot has a pot-like shape with a deep hollow space and is synthesized in series with the appearance of fiber. Therefore, we expect that the new material can be applied in various fields as fibers as well as pieces.
