Which mechanism causes amplified piezoelectric response in perovskite crystals near a morphotropic phase boundary?

💡 Explanation

Enhanced piezoelectricity near morphotropic phase boundaries arises because polarization rotation allows large strain changes with minimal energy input, therefore resulting in dramatic piezoelectric response, rather than the creation of defects or solely energy considerations.
