Which outcome occurs when exceeding the voltage limit in a ferroelectric capacitor?

A)Reduced polarization switching threshold
B)Increased data retention stability
C)Ferroelectric domain wall pinning
D)Increased depletion region gap creation

💡 Explanation

An excess will cause dielectric breakdown through impact ionization; rather than the designed switching of polarization, the increased electric field causes new electron-hole pairs and widening of the depletion layers. Therefore, insulation fails rather than other changes.
