Perspectives and challenges in multilayer ceramic capacitors for next generation electronics
TL;DR: In this article, a review of state-of-the-art synthesis and design of BaTiO3-based dielectric materials for multilayered ceramic capacitor (MLCC) applications is presented.
Journal ArticleDOI
Effect of Acceptor (Mg) Concentration on the Resistance Degradation Behavior in Acceptor (Mg)‐Doped BaTiO3 Bulk Ceramics: I. Impedance Analysis
TL;DR: In this paper, the electrical resistance of acceptor-doped BaTiO3 ceramics was compared against different acceptor concentrations and an impedance spectroscopy study was conducted on these samples at various temperatures.
Journal ArticleDOI
Correlation Between Resistance Degradation and Thermally Stimulated Depolarization Current in Acceptor (Mg)-Doped BaTiO3 Submicrometer Fine-Grain Ceramics
TL;DR: In this article, the thermally stimulated depolarization current (TSDC) of acceptor-doped BaTiO3 ceramics was analyzed for submicrometer fine grain specimens.
Journal ArticleDOI
Effect of Acceptor (Mg) Concentration on the Resistance Degradation Behavior in Acceptor (Mg)‐Doped BaTiO3 Bulk Ceramics: II. Thermally Stimulated Depolarization Current Analysis
TL;DR: In this article, the acceptor ionization energy was estimated to be about 1.0 eV and the activation energy of the oxygen vacancy relaxation showed roughly constant values of ∼0.9 eV, irrespective of acceptor concentration.
Journal ArticleDOI
Influence of grain size on impedance spectra and resistance degradation behavior in acceptor (Mg)-doped BaTiO3 ceramics
TL;DR: In this paper, the effect of acceptor concentration in (Mg)-doped BaTiO3 on the resistance degradation behavior was contrasted between coarse- and fine-grain samples with ∼90 and ∼0.8 μm in size, respectively.
