A03 Computational & Data Science

Theoretical, computational & data science studies on mechanisms of interface-ionics


We investigate equilibrium/steady states and dynamics of electrons and ions around solid-solid interfaces via multi-scale type computational approaches between DFT level and continuum model as well as data-driven AI science approaches. Finally, we address to construct new theoretical framework for interface ionics.

Research subjects
  1. Computational analysis of equilibrium/steady state of electrons and ions around solid-solid interfaces.
  2. Data-driven AI analysis of interfacial properties in conjunction with experimental data.
  3. Establishment of more appropriate theoretical framework for interface ionics.

A04 Design of Functional Interface

Development of New Solid State Ionics Materials through Design of Functional Interface


New functionality of materials is emerged when interface is formed between crystalline and amorphous materials. In this study, composite materials consisting of crystalline and amorphous materials are systematically studied, and the origin of new functionality for composite materials is also examined.

Research subjects
  1. Development of material synthesis procedures with highly designed interface (and grain boundary)
  2. Realization of “new” functionality of solid state ionics materials through the design of interfacial structures
  3. Study on new solid state devices with ionics materials, for instance, solid state capacitors, solid sate actuator etc.
