Large Electrocaloric Effect in Stretched Relaxor Ferroelectric Polymers near Morphotropic Phase Boundary

Chemistry
Use of the morphotropic phase boundary (MPB) is a promising approach to enhance the electrocaloric effect in ferroelectric polymers. This is usually achieved by a composition method, and polymer processing near the MPB to tune electrocaloric response has

Nanoscale ferroelectric/relaxor composites: Origin of large strain in lead-free Bi-based incipient piezoelectric ceramics

, 2016
La-doped (Bi0.5Na0.41K0.09)TiO3 ceramics were synthesized using a conventional solid-state reaction route. X-ray diffraction and electric-field-induced polarization studies revealed a phase transformation from a ferroelectric to a relaxor with increasing
