Polaron-Defect Complexes Point to Ultrahigh Piezoelectricity
Key Takeaways
- A paper titled "Ultrahigh piezoelectricity by polaron-defect complexes" appears in Science, volume 394, issue 6819, pages 118-124, dated October 2026.
- The title claims that coupling between polaronic charge states and clustered crystal defects can produce piezoelectric performance described as ultrahigh.
- Polarons are charge carriers accompanied by local lattice distortion, and their physics shares the same charge-strain coupling that underpins piezoelectricity.
- Defect complexes differ from isolated defects by carrying net dipoles, preferred orientations and distinct local strain fields that can be engineered.
