Metal-halide perovskite-type materials are a new semiconductor family. It has
been revealed that these materials are promising for solar-cell applications.
However, fundamental properties of these materials are not clearly understood.
We are now studying fundamental properties and novel crystal growth techniquesof metal-halide perovskite-type semiconductors in order to realize innovative
photonic devices.

My research theme during my graduate school
years was organic nonlinear optical crystals.
After several turning points, I shifted myresearch focus to semiconductor materials andultimately arrived at studying metal halide

Materials without a periodic structure, such as soft matter and amorphousmaterials, have unique mechanical and thermal properties that differ significantly
from crystals and contribute to humankind in various fields. Until now, research on
disordered systems has been based on the center-of-mass structure of particles,
but the physical characteristics of these systems remain elusive. To overcome
this situation, in addition to the conventional thermodynamic viewpoint, we arechallenging to elucidate the structural features of non-equilibrium solid-statematerials, such as glasses and gels, as well as the physical mechanisms behind
universal and unique mechanical and thermal properties of these materials, froma new kinetic viewpoint of “mechanical self-organization” .
