研究分野 plasticity of crystalline, quasicrystalline and amorphous solids, physical properties of dislocations, photonic amorphous materials and photonic quasicrystals


Physical properties of dislocations are investigated. Growth mechanism and physical properties ofquasicrystals, which possess a peculiar type of structural order, are also the subjects under investigation. Recently, researches on photonic amorphous materials and photonic quasicrystals are also conducted. Current topics are:
a) Physical properties of dislocations in topological insulators
b) Growth mechanism of quasicrystals
c) Photonic amorphous materials and photonic quasicrystals
