抄録/ポイント： いくつかの鉛フリー圧電は,非常に過酷な高温環境における応用の要求を満たすことができない。本研究では,Na_0.5Bi_4.46Ce_0.04Ti_4-xCo_xO_yセラミックにおいて,Ti4+をCo3+に置換することにより,高い圧電係数(d_33)と高いCurie温度(T_c)を有する強化圧電性能を達成した。Co3+の導入はB-O結合長を減少させ,BO_6八面体と格子体積の収縮をもたらした。B-O結合の電子局在化度およびBO_6八面体の極性は,格子体積の減少によって同時に改善され,これは第一原理計算によって示した。したがって,x=0.02molのNa_0.5Bi_4.46Ce_0.04Ti_4-xCo_xO_yセラミックにおいて,22pC/Nの高い圧電係数と690.2°Cの高いT_cを実現した。本研究は,非常に厳しい環境における実用化のための超高温圧電デバイスを設計するための良好なパラダイムを与える。Copyright 2022 Elsevier B.V., Amsterdam.
