测量了无规聚苯乙烯薄膜在不同电压和温度下的稳态电导率。薄膜的厚度为33-40微米，施加的电压为20-900伏。在施加电压后有足够的时间，以确保在测量之前有稳定的电流。得到了电流与电压的关系以及电流与温度的关系。结果一致地假设电流是由注入到薄膜中的电子组成的，该电子包含空间电荷越过肖特基势垒并向阳极扩散。对陷阱密度作了粗略估计，发现随着温度的升高，陷阱密度减小。并对该过程的表观活化能进行了讨论。
A measurement of steady-state conductivity was carried out on atactic polystyrene films at various voltages and temperatures. The thicknesses of the films were 33–40 µm and the voltages applied were 20–900 volts. A sufficient time was allowed to elapse after the application of the voltage to ensure a steady current before measurement. A relation between the current and voltage and also that between the current and temperature were obtained. The results were consistently explained on the assumption that the current is composed of electrons injected into the film which contains space charge over the Schottky barrier and diffusing toward the anode. A rough estimate was made of the density of traps which was found to decrease with increase in the temperature. A discussion is given also on the apparent activation energy of the process.
