Due to the local symmetry-breaking caused by the change in polarization, domain walls are found to possess an unexpected lateral piezoelectric response, even when this is symmetry-forbidden in the parent material. This has interesting potential applications in electromechanical devices based on ferroelectric domain patterning. Moreover, electrical conduction is shown to arise at domain walls in otherwise insulating lead zirconate titanate, the first such observation outside of multiferroic bismuth ferrite, due to the tendency of the walls to localize defects. The role of defects is then explored in the theoretical framework of disordered elastic interfaces possessing a characteristic roughness scaling and complex dynamic response. It is shown that the heterogeneous disorder landscape in ferroelectric thin films leads to a breakdown of the usual self-affine roughness, possibly related to strong pinning | | 出版日期 | Book 2014 | | 关键词 | Atomic Force Microscopy; Characteristic Roughness Scaling; Defect Localization at Domain Walls; Disorde | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-319-05750-7 | | isbn_softcover | 978-3-319-38277-7 | | isbn_ebook | 978-3-319-05750-7Series ISSN 2190-5053 Series E-ISSN 2190-5061 | | issn_series | 2190-5053 | | copyright | Springer International Publishing Switzerland 2014 |
