Investigation for high-performance of semiconductor thermoelectric materials and TiO2 photocatalyst

I will give a presentation on research results by experimental and first-principles calculations for the performance enhancement of semiconductor thermoelectric materials and TiO₂ photocatalysts over many years. First, I will talk the research background, followed by an introduction to experiments and first-principles calculations for TiO₂₋᙮ and TiₙO₂ₙ₋₁ thermoelectric materials, alongside experiments and first-principles calculations for TiO₂₋᙮ photocatalysts. First-principles calculations are highly effective for analysis of the mechanisms behind enhancing the performance of both thermoelectric materials and photocatalysts. Furthermore, I will introduce the use of first-principles calculations for selecting candidate materials within the Ni-M-Al Heusler alloy thermoelectric material family. The presentation will be in Japanese.
