Raman investigations of the crystal lattice dynamics in classical ferroelectric perovskites
SrTiO 3, PbTiO 3, and BaTiO 3 have been analyzed. The specific features revealed in the …

A review of the properties of ferroelectric materials that are relevant to microwave tunable
devices is presented: we discuss the theory of dielectric response of tunable bulk materials …

The marriage between a 2D layered material (2DLM) and a complex transition metal oxide
(TMO) results in a variety of physical and chemical phenomena that cannot be achieved in …

Understanding the behaviour of the dielectric constant in ferroelectric thin films remains a
challenging problem. These ferroelectric materials have high static dielectric constants, and …

Thorough Raman and infrared (IR) reflectivity investigations of nominally pure SrTiO 3
ceramics in the 10–300 K range have revealed a clear presence of the polar phase whose …

First-principles calculations based on the density function theory (DFT) are implemented to
explore the effect of Cu do** on the structural, electronic and optical properties of SrTiO 3 …

Raman spectroscopy was used to demonstrate that the lattice dynamics of SrTiO3 (STO)
nanoparticles strongly depends on their microstructure, which is in turn determined by the …

The temperature and thickness dependence of permittivity of (Ba, Sr) TiO 3 has been
investigated. The films were deposited by liquid-source metalorganic chemical vapor …

The effect of in-plane strain on the nonlinear dielectric properties of SrTi O 3 epitaxial thin
films is calculated using density-functional theory within the local-density approximation …

We have studied lattice dynamic properties of SrTiO 3 thin films from 5 to 300 K using metal-
oxide bilayer Raman scattering. First-order zone-center optical phonons, symmetry …
