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 …

The functionality enhancement of ferroelectrics by local polar clusters called polar
nanoregions (PNRs) is one of the current interests in materials science. KTa1− x Nb x O3 …

In this work, the structural, elastic, electronic, photocatalytic and optical properties of BaTi 2
O 5 have been explored using density functional theory (DFT). A comprehensive study of …

In a semi-review paper, we show that the local pseudo-Jahn–Teller effect (PJTE) in
transition metal B ion center of ABO3 perovskite crystals, notably BaTiO3, is the basis of all …

In this work, lead-free BaZr 0.35 Ti 0.65 O 3 (BZT) thin films were grown on silicon by using
pulsed laser deposition. The phase structures of the BZT thin films were controlled via the …

Explaining the properties and functions of materials in terms of their atomic arrangements
and inhomogeneous structures is a fundamental challenge for the development of …

Perovskite ferroelectrics play an essential role in modern science and technology. The
excellent properties of perovskites are closely related to their lattice dynamics. Potassium …

In spite of more than 60 years of research, hundreds of publications, and dramatic influence
on properties, the driving force of the formation of the polar nanoregion (PNR) in the …

Compositional tuning in materials at the morphotropic phase boundary has been a novel
strategy to realize unprecedented and exotic physical properties. This work reports the …

The frequency dependence of the coercive field E c in [001] c poled 0.71 Pb (Mg 1/3 Nb 2/3)
O 3–0.29 PbTiO 3 single crystals was investigated as a function of frequency f from 0.01 Hz …
