In this work, we explore the origin and type of charge carriers, and their transport mechanism in polycrystalline barium-iron-niobate (BFN, BaFe$_{0.5}$Nb$_{0.5}$O$_3$) ceramics, at lower temperatures between 20K and 300K. The observed point defects

Barium titanate BaTiO3 is one of the most ferroelectrics. Its commonly used in capacitors due to its high dielectric constant. In this study, our goal is to determine the extent to which the change in the average ionic radius of A, B sites affects th

To investigate the effect of Er 3+ doping on the luminescence behavior of perovskite structure ceramics, the Er 2 O 3 doped KNbO 3 smart ferroelectric ceramics have been synthesized by the conventional solid-state reaction. The results of luminescenc

A Ginzburg–Landau theory for the multiple structural phase transition observed in the cuprate perovskite structure ceramics is developed. The order parameters Λi for each phase are defined in terms of the deformations which occur in each phase. In

Cracking of ceramics with tetragonal perovskite grain structure is known to appear at different sites and scale level. The multiscale character of damage depends on the combined effects of electromechanical coupling, prevailing physical parameters an
