As the BaTiO3 dielectric layer of multi-layer ceramic capacitors (MLCCs) becomes thinner, the problem of leakage current degradation arises. In this study, the leakage current degradation was investigated for the cases when the Ni–Sn internal elect

We investigated domain structures in Pb(Zr,Ti)O3(PZT) ceramics whose composition lies on the morphotropic phase boundary (MPB) using transmission electron microscopy (TEM) and evaluated the piezoelectric properties of PZT. We found that monoclinic na

An investigation has been made on the state of barium titanate (BaTiO3; BTO, hereafter) nanoparticles of 10-15 nm in diameter dispersed in various suspension media, such as 2-methoxyethanol (ethylene glycol monomethyl ether: EGMME) with and without a

Epitaxial assembly involved in the formation of aggregates of single-crystalline barium titanate (BaTiO3) nanoparticles under hydrothermal condition is reported. The aggregates of BaTiO3 nanocrystals were synthesized by heating a mixture of barium hy

We successfully obtained Sn-doped SrTiO${}_{3}$ (SSTO) perovskites, and clarified their ferroelectricity and structural properties by using first-principles theoretical calculations. The ferroelectricity of SSTO was confirmed by the appearance of a d

We clarified the effect of (Ba,Ca)/Ti ratio on the substitution of Ba by Sn in (Ba,Ca)TiO3 perovskites. With decreasing (Ba,Ca)/Ti ratio, c/a ratio rapidly increases and leads to an increase in phase transition temperature. The increasing number of B
