The review provides a comprehensive overview on the major findings regarding ion
redistribution at interfaces in oxide systems and its effects on the electrical transport …

The Gerson–Marshall (1959) relationship predicts an increase in dielectric breakdown
strength (BDS) and therefore, recoverable energy density (Wrec) with decreasing dielectric …

Barium titanate is widely used in the fabrication of thermistors with a positive temperature
coefficient of resistivity (PTCR). The resistivity can increase by several orders of magnitude …

There has been much recent interest in a so-called “giant-dielectric phenomenon” displayed
by an unusual cubic perovskite-type material, CaCu 3 Ti 4 O 12; however, the origin of the …

Multiferroics composite materials have been widely used in several applications, such as
ceramic supercapacitors and multifunctional and active devices, owing to their high …

Chemical doping is one of the major methods by which the properties of BaTiO 3 are
modified to induce various device characteristics. Doping strategies are generally separated …

Oxygen-vacancies-related dielectric relaxation and scaling behaviors of Bi 0.9 La 0.1 Fe
0.98 Mg 0.02 O 3 (BLFM) thin film have been investigated by temperature-dependent …

A review is given of the origins of high permittivity in two groups of materials, La-doped
BaTiO3 and a new barrier layer capacitor material, CaCu3Ti4O12. Factors that influence …

Tetrahedral units can transport oxide anions via interstitial or vacancy defects owing to their
great deformation and rotation flexibility. Compared with interstitial defects, vacancy …

The mechanism of doping BaTiO 3 with La has been investigated by a combination of X-ray
diffraction, electron probe microanalysis, scanning and transmission electron microscopy …
