Outline of Final Research Achievements

High-energy synchrotron radiation X-ray powder diffraction measurement were performed to clarify the relationship between macroscopic distortion and microscopic crystal structure change of lead-free piezoelectric perovskite-type materials. Lead-free piezoelectric ceramics were fabricated and the X-ray diffraction pattern changes were observed as a function of the electric field. A crystallographic characteristic to understand the mechanism of large electric-field-induced distortion has been discussed.

Academic Significance and Societal Importance of the Research Achievements

鉛フリーの材料開発は人類共通の喫緊の課題である。この研究では、圧電素子への応用が可能な高性能なペロブスカイト型酸化物の創製を目指し、さらにその性能を原子レベルで理解するために最先端の放射光技術を開発しミクロな機構を議論した。ここで開発された物質や測定技術を発展・応用することにより、さらなる高機能な圧電体材料の開発に寄与することができることに意義がある。
