Abstract
An analytical, microscopic treatment which can correctly describe the relaxation process of hopping ionic conduction from the adiabatic region to the isothermal region with equal rigor has been developed in interacting lattice gas systems. It is demonstrated that the relaxation motion of a single particle in the assembly is intrinsically non-Debye and follows the Kohlrausch-Williams-Watts (KWW) relaxation behaviour even without interactions among mobile ions. This is an apparent contrast to the current view that the anomaly is “created” by interaction and disorder. Some conclusions with respect to the universal dynamic response observed in solid electrolytes are drawn from results of the analytical treatment.
