Lead halide perovskites are extensively investigated as efficient solution-processable
materials for photovoltaic applications. The greatest stability and performance of these …

Long‐range ordering of dipoles is a key microscopic signature of ferroelectrics. These
ordered dipoles form ferroelectric domains, which can be reoriented by electric fields …

Feature size is a natural determinant of material properties. Its design offers the
technological perspectives for material improvement. Grain size, crystallite size, domain …

Relaxor ferroelectrics were discovered almost 50 years ago among the complex oxides with
perovskite structure. In recent years this field of research has experienced a revival of …

A model of relaxor ferroelectrics based on the interacting polar clusters picture has been
formulated. The electric dipole moment of a nanosized polar domain is allowed a large …

Relaxor ferroelectricity is one of the most widely investigated but the least understood
material classes in the condensed matter physics. This is largely due to the lack of …

Dielectric and Raman scattering experiments were performed on various ceramics with
composition Ba (Ti 1-x Zr x) O 3. Such lead-free, environmental-friendly materials were …

The (1− x) Ba Ti O 3–x Ba Sn O 3 (0⩽ x⩽ 0.30) perovskite solid solution ceramics were
prepared by solid state reaction and studied by dielectric spectroscopy. The complex …

A physical mechanism for the freezing of polar nanoregions (PNRs) in relaxor ferroelectrics
is presented. Assuming that the activation energy for the reorientation of a cluster of PNRs …
