High-performance wavelength-conversion devices using III-V compound semiconductors
We have been working on wavelength-conversion devices utilizing optical nonlinearities of III-V compound semiconductors. Superior properties of these materials are expected to lead to higher performances compared to conventional devices based on oxide dielectrics. We are developing wavelength conversion devices using a novel crystal growth technique, sublattice reversal epitaxy, we have developed for fabricating nonlinear optical devices.
Metal-halide perovskite-type semiconductors
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 techniques of metal-halide perovskite-type semiconductors in order to realize innovative photonic devices.
Challenge from mechanical self-organization to elucidate the physical properties of nonequilibrium soft matter/amorphous material (Tanaka group)
Materials without a periodic structure, such as soft matter and amorphous materials, 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 are challenging to elucidate the structural features of non-equilibrium solid-state materials, such as glasses and gels, as well as the physical mechanisms behind universal and unique mechanical and thermal properties of these materials, from a new kinetic viewpoint of “mechanical self-organization”.
