This paper provides a review of a systematic micro‐Raman scattering study on various lead‐
and barium‐based ABO3 perovskites (A= Pb, La, Ba, Sr, Ce, Gd, Nd and B= Ti, Zr) …

Recent progress in the development of barium strontium titanate thin film varactors for room
temperature tunable microwave devices applications is reviewed, with emphasis on efforts …

Highly efficient Z-scheme MoO3–SrTiO3 heterostructured nanocatalytic systems were
engineered via a sol–gel chemical route and exploited in green H2 energy synthesis via …

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 …

The codo** effect of antimony on the photocatalytic activity of visible-light-driven SrTiO 3
doped with rhodium (SrTiO 3: Rh) was investigated. SrTiO 3 doped with rhodium and …

Phonons play a key role in the physical properties of materials, and have long been a topic
of study in physics. While the effects of phonons had historically been considered to be a …

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 …

We carry out first-principles density-functional calculations of the antiferrodistortive (AFD)
and ferroelectric (FE) soft-mode instabilities in tetragonal SrTiO 3, with the structural degrees …

We fabricated an epitaxial Au/SrTiO 3 (001)/SrRuO 3 (or CaRuO 3)(001)/SrTiO 3 (or LaAlO
3)(001) heterostructure to investigate the effect of the strain on the epitaxial tunable dielectric …
