| Outline of Final Research Achievements |
In this study, we performed numerical simulations to investigate the buckling behavior of nanostructured materials subjected to external loading from the point of view of mechanical and physical properties. Our atomistic structural instability analyses revealed the mechanisms of axial and radial buckling deformations in carbon nanotubes and boron nitride nanotubes. We also calculated change in electron-oriented physical properties due to buckling deformation by means of semi-empirical quantum mechanics calculations. The calculations clarified relationship between such change in functional aspects and buckling deformation modes. In addition, we established a framework of atomistic simulations for the analysis of multi-physics phenomena in ferroelectric nanostructured materials.
