Schematic diagram of defect construction, ferroelectric hysteresis loops, unipolar strain loops, and hysteresis performance comparison for B(1−x)ST−xSb ceramic compositions. (IMAGE)
Caption
The crystal image on the left illustrates the defect construction process in the ceramic. Through A-site barium vacancy defects and B-site antimony acceptor doping defects, a defect complex is ultimately formed. The ferroelectric hysteresis loops and strain hysteresis loops on the right demonstrate the most critical performance characteristics—the nearly overlapping strain loops exhibit near-zero strain hysteresis. Finally, the strain hysteresis performance comparison chart showcases the performance advantages of this ceramic composition, which are clear and intuitive, reflecting a strong competitive edge in performance.
