Electrical Nanoscale Training of Piezoelectric Response Leading to Theoretically Predicted Ferroelastic Domain Contributions in PZT Thin Films
Piezoelectric contributions from mobile 90° domains are locally activated by electrical training of a PZT thin film. The high response state of 160 pm V−1 corresponds well with theoretical predictions. This state relaxed at modest trainings within minutes but was stabilized after extensive training....

Summary: | Piezoelectric contributions from mobile 90° domains are locally activated by electrical training of a PZT thin film. The high response state of 160 pm V−1 corresponds well with theoretical predictions. This state relaxed at modest trainings within minutes but was stabilized after extensive training. Our findings indicate that dramatic domain reconfigurations must take place. |
