|Title:||Effect of high electric field on conduction of TeO2-V2O5-MoO3 amorphous thin films|
|Abstract:||The effect of high electric field on de conductivity of TeO2-V2O5-MoO3 thin films has been studied. At low fields, the electrical conduction is ohmic while, at high fields, samples how non-ohmic behavior, The current-voltage characteristics show increasing deviation from Ohm' s law, with increasing current density, leading to the maximum voltage. This critical behaviour is described as switching phenomenon, for this material, the non -ohmic behaviour (Pool - Frenkel effect) occurs at electrical fields of about 104- 105 (V/cm).|
