Impedance Description of the Processes of Electromigration in a Substance

Аннотация

Equivalent electrical circuits for all types of electromigration are proposed: pass-through conductivity, fast polarization processes, and relaxation polarization. The principle of the superposition of currents allows circuits to be designed with the simultaneous development of several processes of electromigration. The possibility of identifying the processes of electromigration developing in a substance from the experimental impedance spectra is discussed.
