The ferroelectric domains of tetragonal Pb(ZrxTi1−x)O3 epitaxial thin films have been studied comprehensively to reveal their piezoelectric responses under substrate constraint.
Solid-state interfacial dealloying creates bi-continuous nanostructured thin films with 3D interconnected morphology, revealed by multimodal characterization, offering potential applications in catalysis, biomedical sensing and energy storage.
