In recent times, the triboelectric and piezoelectric effects have garnered significant attention towards developing advanced material composites for energy harvesting sensory applications. this work, potassium sodium niobate (KNN) based films (EF) been developed to utilize mechanical while simultaneously taking advantage of mechanisms. The KNN particles were synthesized using a wet ball milling...

The substitution on either the A- or B-site of ferroelectric perovskites by aliovalent elements has a profound influence their properties. Donor doping “softens” ferroelectrics, whereas acceptor “hardens” them. charge compensation mechanisms are reviewed, as well models describing effects. focus this review is doped-BaTiO3, model lead-free ferroelectric. effects its dielectric, ferroelectric, a...

Glassy dielectric properties were investigated in lead-free BaZr0.4Ti0.6O3 (BZT40) ceramic samples using spectroscopy the frequency range of 0.003 Hz–1 MHz and at temperatures 10 K < T 300 K. Measurements quasistatic polarization bias electric fields up to ~28 kV/cm suggested that a ferroelectric state could not be induced, contrast case canonical relaxors such as PMN. The freezing dynamics ...
