Which outcome occurs when excess charge accumulates non-uniformly on an ionic crystal surface?

💡 Explanation

When excess charge accumulates non-uniformly, it generates an electric field gradient, as pyroelectricity creates a transient voltage during periods of heating or cooling due to changes in the crystal lattice polarization temperature causes lattice vibrations driving charge movements thereby enabling current pulse generation. Therefore a pyroelectric current pulse results, rather than dielectric strengthening, mobility increase or conductivity boosts which require different external conditions and mechanisms.
