Over the 100 years since the discovery of the diffraction of X-rays by crystals, structure
determination based on the analysis of Bragg peaks has grown into a very precise, widely …

Polarized Raman, IR, and time-domain THz spectroscopy of orthorhombic lead zirconate
single crystals have yielded a comprehensive picture of temperature-dependent …

Antiferroelectric PbZrO3 has attracted renewed interest in recent years because of its unique
properties and wide range of potential applications. However, the nature of …

The prototypical antiferroelectric PbZrO 3 has several unsettled questions, such as the
nature of the antiferroelectric transition, a possible intermediate phase, and the microscopic …

In the archetypal antiferroelectric PbZrO 3, antiparallel electric dipoles cancel each other,
resulting in zero spontaneous polarization at the macroscopic level. Yet in actual hysteresis …

Antiferroelectrics are under extensive reexamination owing to their unique properties and
technological promise. Computationally, they pose a challenge for predictive modeling as …

Antiferroelectric perovskites form an important family of functional electric materials, which
have high potential in energy storage and conversion applications. However, a full …

The ability to generate efficient giga–terahertz coherent acoustic phonons with femtosecond
laser makes acousto-optics a promising candidate for ultrafast light processing, which faces …

We report the results of a comprehensive study of the critical dynamics of the classical
perovskite antiferroelectric PbZrO 3. The combination of inelastic x-ray and diffuse x-ray …

A combined neutron diffuse scattering study and model analysis of the antiferroelectric
crystal PbZrO3 is described. Following on from earlier X-ray diffuse scattering studies …
