Abstract
The AC conduction in thin potassium iodide films in the range 5 Hz to 20 kHz has been studied for applied voltages between 0.4 and 1.2 V at room temperature. The universal dielectric response sigma =b omega n for AC conductivity is obeyed for all the applied voltages. Taking into consideration the linearity in the AC conductivity and the nature of the potassium iodide films, previous results on the transient electrical conductivity of thin potassium iodide films are analysed and resolved into two components, one of which is associated with ionic conductivity and the other with the Poole-Frenkel effect.
