Nanoionics: ionic charge carriers in small systems

Abstract

Ion-conduction phenomena are discussed that are governed by interfacial effects. In a given material the density of interfaces is crucial in such cases. Particular emphasis is laid on situations in which the spacing of interfaces matters, even locally. These then observed mesoscopic phenomena are at the heart of what may be called nanoionics. Effects do not only refer to enhancement or depression of conductivity or storage, mechanistic variations are also observed.
