Research Interests
  • Interface structure and electrical property of semiconductor ceramics
    Micro-/Nano-scale structure of ferroelectrics
    Microstructure analysis of solid state materials
    keyword : Grain Boundary/Interface, Ferroelectrics, Semiconducting ceramics, Electron microscopy
    2014.04～2025.04.
Current and Past Project
  • In the present research, we use transmission electron microscopy to understand the response of domain structure and atomic arrangement in ferroelectric material by applying external electric field.
  • Microstructure of various ceramic materials are analyzed.
  • In this research project, we use first-principles calculation to explore the future transparent electrodes.
    This project is carried out as a part of Global Science Campus project of Kyushu University.
  • Current-voltage characteristic and microstructure, in particular, grain-boundary structure, which is used for varistor, is investigated.
