In this study, we investigate the atomic structure and conductivity of nominally neutral 180° DWs artificially created in an epitaxial thin film of tetragonal PbZr0.1Ti0.9O3. Using piezoresponse force microscopy and scanning transmission electron microscopy, we elucidate the complex structure of these 180° DWs and their coupling with ferroelastic domains, revealing that they exhibit a complex structure due to the strain-mediated interplay with the ferroelastic domains. Our results demonstrate that the 180° DWs conductivity is associated with the emergence of polar discontinuities, including the formation of tail-to-tail charged segments, which has been further confirmed by electron energy loss spectroscopy. Additionally, we investigated the long-term performance of these domain boundaries, demonstrating their unique mobility and structural stability. Our findings provide insights into the atomic-scale mechanisms that turn nominally neutral DWs into highly conductive channels, paving the way for their use in advanced nanoelectronic devices. info:eu-repo/grantAgreement/ES/AEI/CEX2023-001286-S info:eu-repo/grantAgreement/ES/DGA/E13-23R info:eu-repo/grantAgreement/ES/DGA-FEDER E28-23R info:eu-repo/grantAgreement/EC/H2020/ 861153/EU/Materials for Neuromorphic Circuits/MANIC This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 861153-MANIC info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2020-112914RB-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 8.2 2024 NANOSCIENCE & NANOTECHNOLOGY 31 / 147 = 0.211 2024 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 83 / 461 = 0.18 2024 Q1 T1 1.921 2024 Materials Science (miscellaneous) 2024 Q1 Nanoscience and Nanotechnology 2024 Q1 Medicine (miscellaneous) 2024 Q1 14.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Risch, Felix Pardo, José A.
