Inverse Domain‐Size Dependence of Piezoelectricity in Ferroelectric Crystals
Advances in Materials, 2021 Piezoelectricity of ferroelectric crystals is widely utilized in electromechanical devices such as sensors and actuators. It is broadly believed that the smaller the ferroelectric domain size, the higher the piezoelectricity, arising from the commonly ...

Unconventional piezoelectric coefficients in perovskite piezoelectric ceramics
Journal of Materiomics, 2021 Piezoelectric ceramics exhibit three conventional piezoelectric coefficients, i.e., d33, d31, d15, due to their ∞mm crystal symmetry. Unconventional piezoelectric coefficients, such as d11, d12, d13, d14, d16, etc., can only be extracted from piezoelectric single crystals of special symmetry with specific cut direction.
