摘要：

Thermodynamic analysis shows that 180 degrees ferroelectric domains under an external electric field behave as elastic domains due to the converse piezoelectric effect. The interdomain elastic interaction between 180 degrees ferroelectric domains is an important factor in determining the effective dielectric and piezoelectric responses of thin film constrained by a substrate and therefore cannot be neglected.
