Computational investigations on the Kohlrausch empirical law in interacting systems

In many nano- and microcrystalline or amorphous insulators, semi-insulators, and solid electrolytes, relaxational polarization processes follow stretched exponential functions or power laws in the time domain referred to as Kohlrausch relaxations. For the underlying physical processes we investigated (I) the dipolar interaction and (II) an electrode effect including ionic interactions as possible mechanisms. The calculations were carried out numerically by the use of computer models.
