Tuesday publication post! 📖 In this publication, the #FusionAX system enabled in situ TEM the investigation of ferroelectric domain switching dynamics in a relaxor ferroelectric PMN-PT single crystal under applied electric fields. By combining electrical biasing inside the TEM with quantitative domain analysis, the authors directly correlated nanoscale polarization reversal processes with macroscopic ferroelectric behavior.
Key highlights:
⚡ Fusion AX enabled in situ TEM observation of ferroelectric domain nucleation, growth, and evolution during electrical cycling
📊 Quantitative analysis of domain-area evolution allowed extraction of microscopic polarization reversal velocities and their relationship to macroscopic P–E hysteresis behavior
🔍 The study provides direct visualization of domain switching mechanisms when electric fields are applied non-parallel to the polarization direction, offering new insights into relaxor ferroelectric behavior
This work delivers a comprehensive nanoscale understanding of ferroelectric polarization reversal in PMN-PT single crystals. By linking real-time domain evolution to bulk electrical responses, the study advances our understanding of domain switching kinetics and provides valuable guidance for the development of next-generation piezoelectric and ferroelectric devices.
