Chapter 9 – Anomalous Charge Transport and Polarization in Semiconductors Oxides and Porous Film Electrodes

摘要: This chapter aims at illustrating an exposition of the more simple combination transport and polarization. Frequency-dispersion phenomena are usually understood as transport, or polarization processes that depart from frequency-independent conductivity, in case Debye relaxation, for phenomena. Their evident manifestation consists a power-law-dependence measured physical quantity on frequency ω s , which 0 < 1. Generalized relaxation functions, frequency-dependent constant-phase elements (CPE), low- dispersion behavior all particular instances dependencies dealt with. The strict distinction between separated-unrelated is not adequate some type responses. In water, instance, it clear possible motions protons whether they must be considered charge displacements within molecule, translational motion ions. Anomalous amorphous semiconductors, low-frequency consequence interfacial examples this solid state.
