Abstract

Effect of high electric field on the dc conductivity of TeO2-V2O5-MoO3 amorphous bulk samples with different molar ratio of each component was investigated with gap-type electrode arrangement. At low electric fields, the current-voltage (I–V) characteristics has a linear shape, while at high electric fields (>103 V/cm), bulk samples show nonlinear behavior (nonohmic conduction) and current-voltage characteristics shows increasing deviation from Ohm’s law with increasing current density. High-field effect of Pool-Frenkel type was observed at electrical fields about 103−104 V/cm. In addition, positive deviation from Pool-Frenkel effect was observed when a field higher than about 104 V/cm was applied.
