Outline of Research at the Start

電場 (E)-分極 (P)曲線にヒステリシスを有する強誘電体は、不揮発メモリやスイッチング素子に必要不可欠な材料である。その多くはBaTiO3やPZT (PbTiO3-PbZrO3)などの無機材料であり、レアメタル使用・毒性・コストなどの観点から低エネルギー駆動でSDGsに貢献可能な省エネルギー駆動型の有機強誘電体に注目が集まっている。強誘電体の性能はP-E ヒステリシス曲線における残留分極値 (Pr)と抗電場 (Ec)により決定される。本提案では、新たな分子設計によるPrの自在制御に挑戦し、外部電場によりPrが増幅される「イオンブースト型の有機強誘電体の創製」に挑戦する。

Outline of Final Research Achievements

Ferroelectrics with hysteresis in the electric field (E)-polarization (P) curve are essential materials for nonvolatile memory and switching devices. The performance of ferroelectrics is determined by the residual polarization value (Pr) and the coercive electric field (Ec) in the P-E hysteresis curve, and materials with larger Pr and smaller Ec are advantageous for stable device operation and energy saving. In this proposal, we attempted to hybridize ionic conductivity and ferroelectricity by molecular design of "ion transport + alkylamide chain," and challenged the creation of "ion-boosted organic ferroelectrics" in which Pr is amplified by an external electric field. I designed a channel capable of ionic displacement and coexisted it with ferroelectric alkylamide derivatives.

Academic Significance and Societal Importance of the Research Achievements

無機材料では実現が難しい多様なメカニズムである電荷移動、水素結合、プロトン移動、分子反転などの多様な分極反転メカニズムの設計が有機材料において可能である。今回、新たにイオンチャネル内のイオン変位を利用した強誘電体パラメーターの最適化に成功した。強誘電体ヒステリシスにおける分極値の増加は、オン・オフスイッチング特性を向上し、強誘電体から作られる不揮発性メモリの信頼性を向上させる。有機強誘電体メモリは、軽量化およびそのデバイス構造作成にかかるコスト削減の観点から、次世代の低環境負荷メモリ材料として大きな注目を集め手いることから、多様な動作メカニズムの提唱は、今後のさらなる学術的な発展を可能とする。
