Abstract

The electrical conduction in Ag-polypropylene-Ag sandwich samples is studied measuring the dependence of current (I) on voltage (U) and temperature (T). The experimental results of I–U–T relationships show that Schottky field assisted thermionic emission is the dominant conduction mechanism in the temperature range 390 to 440 K. The metalinsulator work function is calculated to ≈︁ 1.83 eV. Hysteresis and polarization effects are also observed in the I–U characteristics in this range of temperature. Contribution due to bulk polarization is suggested in the conduction mechanism besides the Schottky emission. Die elektrische Leitfähigkeit in Ag-Polypropylen-Ag-Sandwichproben wird durch Messung der Abhängigkeit des Stromes (I) von Spannung (U) und Temperatur (T) untersucht. Die experimentellen Ergebnisse der I–U–T-Beziehungen zeigen, daß die durch das Schottky-Feld assistierte thermische Emission der dominierende Leitungsmechanismus im Temperaturbereich von 390 bis 440 K ist. Die Metall-Isolator-Austrittsarbeit wird zu etwa 1,83 eV berechnet. Hysteresis- und Polarisationseinflüsse werden in den I–U-Charakteristiken in diesem Temperaturbereich ebenfalls beobachtet. Es wird angenommen, daß neben der Schottky-Emission ein durch Volumenpolarisation hervorgerufener Beitrag zum Leitungsmechanismus existiert.
