Outline of Final Research Achievements

In-situ transmission electron microscopy was used to observe the microstructural changes of SiC nanotubes under ion irradiation. The nanotubes possess better resistance against amorphization by irradiation, having a higher critical irradiation dose at room temperature. Surprisingly, the lattice plane spacing of SiC nanotube shrinks by approximately 1.1% after irradiation at 700 degree C, although the nanotube volume swells slightly. This is a counterintuitive result.
From the result of electrical characteristics evaluation of SiC nanotubes, SiC nanotubes exhibit nonlinear current-voltage curve like varistors.

Academic Significance and Societal Importance of the Research Achievements

材料をナノメーターサイズにすることで、バルク材料とは異なった諸特性を持つことが期待されている。SiCは、元々、耐照射特性に優れている材料であることが知られているが、ナノチューブ化することで、さらに耐照射特性の向上が見込まれることを明らかにしたことは、工学的に重要な成果であるといえる。また、イオン照射により、SiCナノチューブがバルクSiCとは異なる微細組織変化を示すことを世界で初めて明らかにしたことは、学術的にも意義深いと考えている。
