Abstract

Precise design of architected functional ceramics hinges on a fundamental understanding of their structure-property relations. Functional properties in ferroelectric ceramics are known to be strongly nonlinear with respect to electric-field amplitude due to microscopic mechanisms, such as domain-switching. However, unlike monolithic ceramics, since electric-field distribution within architected ferroelectrics is itself non-uniform, it is essential to re-evaluate how different geometric forms affect their structure-property relations. Here, we show that the figures of merit (FoM) for dielectric and electromechanical responses of architected BaTiO3 ceramics can be enhanced by a factor of ∼5 through a change in geometry. From...

Precise design of architected functional ceramics hinges on a fundamental understanding of their structure-property relations. Functional properties in ferroelectric ceramics are known to be strongly nonlinear with respect to electric-field amplitude due to microscopic mechanisms, such as domain-switching. However, unlike monolithic ceramics, since electric-field distribution within architected ferroelectrics is itself non-uniform, it is essential to re-evaluate how different geometric forms affect their structure-property relations. Here, we show that the figures of merit (FoM) for dielectric and electromechanical responses of architected BaTiO3 ceramics can be enhanced by a factor of ∼5 through a change in geometry. From insights gained using finite element simulation and in situ X-ray micro-diffraction, we show that tunability of electromechanical properties in architected ferroelectric ceramics originates from geometry-specific spatial progression of 90° domain switching, which depends not only on internal electric-field distribution, but also additional factors such as depolarization fields and internal stresses.
