Which phenomenon increases when pulsed current flows through nanoscale capacitor dielectrics?

💡 Explanation

When pulsed current flows, high electric fields cause electromigration because ions gain kinetic energy and momentum transfer leads to accelerated movement and dislocation formation in the dielectric, weakening the structure. Therefore electromigration increases, rather than other mechanisms based on heat, quantum effects, or oxidation under these transient electrical conditions.
