영문 초록

In line with the trend towards electrification in mobility, there is a demand for the development of nextgeneration Multilayer Ceramic Capacitors(MLCCs) with superior properties compared to those using the conventional BaTiO3 (BT) ceramics. For this, various high-performing ferroelectric ceramics have been proposed as post-BT materials, and numerous studies have been conducted on the role of oxygen vacancies within these materials. It has been confirmed that oxygen vacancies in the ceramic material have a significant impact on various properties such as oxygen ionic conduction, IR degradation, microstructure, aging degradation, and hardening effect, and by controlling the concentration and mobility of oxygen vacancies, it is possible to adjust these properties. We hope that research on the role of oxygen vacancies in various high-performing ferroelectric ceramics will be utilized as a foundation of knowledge for the development of next-generation MLCCs in the future.
