|I have been working on the synthesis and characterization of boron-based materials since I was a doctoral student. As boron lacks valence electrons, the crystal structure of the same binary borides changes in various structures according to the ratio of the [metal]/[boron]. These structural changes and complex structures result in the creation of various physical properties. So far, I have been synthesizing borides for thermoelectric materials and super-hard materials. The main results include the control of p-type conduction or n-type conduction in YAlB14-based materials through the control of Al occupancy in YAlB14 compound and the evaluation of mechanical properties of Mo2NiB2-based hard materials from both first-principles calculations and experimental methods.
These studies are based on material synthesis and crystal structure characterization, such as Rietveld refinement, which are my areas of expertise. I am particularly interested in the creation of new physical properties through the control of crystal structure. I am working on creating new materials that do not exist in the world and the synthesis of materials, which exhibit unconventional performance in mechanics or thermoelectric.
