Polarization in Ferroelectric Materials

Introduction to Polarization in Ferroelectric Materials

Polarization in ferroelectric materials (P) is calculated as the product of the electric field (E) applied to the material and the dielectric constant (ε) of the material. The dielectric constant is a measure of a material's ability to store electrical energy in an electric field. Ferroelectric materials demonstrate a spontaneous polarization that can be reversed by applying an external electric field.

Parameter usage:

• electricField = Magnitude of the external electric field applied to the ferroelectric material, measured in volts per meter (V/m).
• dielectricConstant = Dielectric constant (relative permittivity) of the ferroelectric material.

Example valid values:

• electricField = 500 V/m
• dielectricConstant = 20

Output:

• polarization = Polarization value of the ferroelectric material under the applied electric field, measured in coulombs per square meter (C/m²).

Data validation

Both the electric field and the dielectric constant must be greater than zero to ensure meaningful physical properties are quantified.

Summary

This formula calculates the polarization (P) in ferroelectric materials, taking into account the external electric field and the material's dielectric constant, illustrating the material's ability to store electrical energy.
