TL;DR: The enhancement in the dielectric properties suggests that the strategy for optimizing a ceramic solid solution enables the design of better high- performance capacitors and should be generalizable for designing high-performance dielectrics and other functional materials that benefit from nanoscale domain structure manipulation.

TL;DR: A slush polar state with multiphase coexistence in lead-free potassium-sodium niobate (KNN) piezoceramics, which shows a novel relaxor behaviour, i.e., frequency dispersion at the transition between different ferroelectric phases, which should also be applicable to other functional materials requiring a slush (flexible) state with respect to external stimulus.

TL;DR: In this article, a synergistic design strategy is proposed to enhance the piezoelectricity in lead-free piezoceramics by flattening the Gibbs free energy density profile, via the coexistence of multiple phases and local structural heterogeneity.

TL;DR: In this article, the dopant induced tetragonal phase and the accompanying high-density nanoscale heterostructures with low-angle polar vectors are responsible for the high dielectric and piezoelectric properties.

TL;DR: In this article, the phase structure, domain structure, and phenomenological theory were studied on both unpoled and poled samples by taking (0.99 − x)(K0.48Na0.52), Nb0.955Sb0, 0.01SrZrO3-x(Bi0.5Ag0.045)O3 − 0.5
