Outline of Research at the Start

本研究では、圧電体薄膜材料の探索に対して行われていた組成制御による相境界の探索という考え方から脱却し、新しいメカニズムとして可逆的なドメイン応答を導入することによって、既存の材料設計にとらわれない巨大圧電体材料の創成を目指す。結晶異方性を持つ材料一般に適用できるこの概念を用いることで、新規非鉛圧電体材料や非ペロブスカイト型結晶構造の圧電体材料の創成を行う。

Outline of Final Research Achievements

This study proposes a new concept using domain switching to improve piezoelectric responses in the film-based piezoelectric materials without searching the morphotropic phase boundary. In lead zirconate titanate, the fine domain structure appeared by performing strong electric field poling, and piezoelectric property increased four times. The calculation study elucidated that this domain structure appears due to the release of the accumulated strain imposed during the cooling process. We obtained superior piezoelectric performance by applying this mechanism to lead-free piezoelectric film, bismuth sodium titanate-barium titanate solid solution film to other reported piezoelectric films. This result validates our new concept for improving piezoelectric properties without a morphotropic phase boundary strategy.

Academic Significance and Societal Importance of the Research Achievements

圧電材料は、センサやアクチュエータに応用されている電子材料であるが、従来使用されてきたチタン酸ジルコン酸鉛は鉛を含むため、圧電材料の非鉛化が求められてきた。本研究では、特に電子材料として今後重要となる膜形態の圧電材料において、従来主として研究されてきた相境界の探索という枠組みを離れて圧電性を向上させる手法の提案を行った。本研究で提案したドメインスイッチングを利用する手法は、強誘電体の特性の一つである異方性を用いることによって圧電性を向上させる手法であり、組成に関係なく適用可能であるため、今後種々の材料への展開させることにより、新たな圧電材料の登場が期待できる。
