Abstract

(Ba,Ca)(Zr,Ti)O3ceramics have attracted interest as lead-free materials with large piezoelectric responses. Here, the authors use an atomistic model to show the electromechanical properties are due to a complex microstructure and polarization fluctuations in the narrowly stable orthorhombic phase.
