Structure, piezoelectric, and ferroelectric properties of BaZrO3 substituted Bi(Mg1/2Ti1/2)O3-PbTiO3 perovskite

Pressure stabilization and piezoelectric properties of polycrystalline perovskite PbZn1/3Nb2/3O3–PbTiO3

An organic-inorganic perovskite ferroelectric with large piezoelectric response.

Molecular piezoelectrics are highly desirable for their easy and environment-friendly processing, light weight, low processing temperature, and mechanical flexibility. However, although 136 years have passed since the discovery in 1880 of the piezoelectric effect, molecular piezoelectrics with a piezoelectric coefficient d33 comparable with piezoceramics such as barium titanate (BTO; ~190 picoc...

Correlations between tetragonality, polarization, and ionic displacement in PbTiO3-derived ferroelectric perovskite solid solutions

We use first-principles density-functional theory calculations to investigate the dependence of tetragonality on local structure in a variety of ferroelectric solid solutions. We demonstrate that tetragonality is strongly coupled to the B-cation displacement and weakly coupled to the A-cation displacement. Examination of various BiMO3 additives to PbTiO3 for different M 3+ ionic sizes reveals t...

Piezoelectric and pyroelectric properties of ferroelectric Langmuir-Blodgett polymer films

Ferroelectric Domain Structure and Local Piezoelectric Properties of Lead-Free (Ka0.5Na0.5)NbO3 and BiFeO3-Based Piezoelectric Ceramics

Recent advances in the development of novel methods for the local characterization of ferroelectric domains open up new opportunities not only to image, but also to control and to create desired domain configurations (domain engineering). The morphotropic and polymorphic phase boundaries that are frequently used to increase the electromechanical and dielectric performance of ferroelectric ceram...
