What is Poole–Frenkel Effect in ZnO:Al Films about?

The document summarizes a study of the electrical properties of ZnO:Al thin films prepared by sol-gel dip-coating with varying concentrations of aluminum. Electrical conductivity was found to be in the range of 0.08-1.39 S/cm for different aluminum concentrations. I-V characteristics showed non-linearity that increased with temperature, which could be explained by the Poole-Frenkel model of thermionic emission. Trapped potentials were calculated for different doping concentrations. Thermoelectric power meas
