In this work, the effect of high electric field on the dc conductivity of TeO2-V2O5-MoO3 thin films is studied. At low fields, the electrical conduction is ohmic while at high fields, samples show nonohmic behavior and current-voltage characteristics shows increasing deviation from Ohm’s law with increasing current density, leading to a maximum voltage; this critical behavior described as switching phenomena. For this material, the non-ohmic behavior (Pool Frenkel Effect) occurs at electrical fields about 104 -105 (v/cm).
