The exploitation of polarization or charge separation in ferroelectric materials has led to remarkable advances in various fields, such as the development of new ultrasound diagnostic devices. Prominently, these ferroelectric materials have led to piezoelectric devices capable of transforming electric signals into mechanical motion. Understanding how the electric polarization is arranged and fluctuates in a material is key to building better devices. However, disorders in the atomic arrangement along with their inhomogeneous structures can lead to irregular charge distribution in specific regions, posing a fundamental challenge to the development of ferroelectric materials.
