Structure-dynamic approach in nanoionics. Modeling of ion transport on blocking electrode

Abstract

The work develops the structure-dynamic approach in nanoionics for detailed description of non-stationary ion-transport processes in irregular potential relief (direct problem) and interpretation of ionic properties and characteristics of nanosystems (inverse problem). Theoretical basis of the structure-dynamic approach, including structural model of interface space charge region, method of hidden variables and the criterion of smallness of external influence is presented. The approach is applied for the computational modeling of ion-transport in the region of ideally polarizable (blocking) solid electrolyte/electronic conductor (SE/EC) heterojunctions in ac and galvanostatic modes of external influence.
