HfO2-based ferroelectrics are promising for scalable memories, neuromorphic systems, and flexible electronics, but their performance is governed by oxygen vacancies that affect phase stability, leakage, wake-up behavior, and domain switching. Existing strategies mainly focus on tuning the overall oxygen-vacancy concent...
