Ferroelectric/Antiferroelectric Pb(Zr0.8Ti0.2)O3/PbZrO3 Epitaxial Multilayers: Growth and Thickness-Dependent Properties

Ab initio study of antiferroelectric PbZrO3 (001) surfaces

We have carried out first-principles totalenergy calculations of bulk and (001) surfaces of PbZrO3. The ground state for bulk PbZrO3 is determined to be the antiferroelectric orthorhombic phase, with the ferroelectric rhombohedral and paraelectric cubic phases being 0.14 and 0.39 eV per formula unit higher in energy, respectively. PbOand ZrO2-terminated (001) surfaces, either clean or when hydr...

Transformation toughening in an antiferroelectric ceramic

Due to a larger specific volume of the ferroelectric phase, the antiferroelectric-ferroelectric transition is believed to have an enhanced toughening effect against fracture. The toughening requires a non-recoverable transformation in the crack process zone. Complementary measurement of the crystal symmetry, dielectric constant, field-induced polarization, and Raman spectrum on ceramic Pb0.99Nb...

cohesion and cohesive devices in a contrastive analysis between ge and esp texts

the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...

Critical scattering and incommensurate phase transition in antiferroelectric PbZrO3 under pressure

Antiferroelectric lead zirconate is the key ingredient in modern ferroelectric and piezoelectric functional solid solutions. By itself it offers opportunities in new-type non-volatile memory and energy storage applications. A highly useful and scientifically puzzling feature of this material is the competition between the ferro- and antiferroelectric phases due to their energetic proximity, whi...
