Space Charge Limited Currents and Trap Distribution in PVC Stabilized with Lead Stearate

摘要

The current-voltage characteristics at different temperatures had been studied for PVC stabilized with lead stearate.At low voltages,Ohm's law is seen to be followed,while at high voltages space-charge-limited current was observed.The obtained results were interpreted in terms of a Schottky emission type of conduction operating over the temperature range studied.By using an analytical method the density of states is calculated.
