研究了Al2O3的实验导电电流随外加电场（高达40 kV mm−1）和温度（从293到403 K）的变化。通过对实验数据进行比较，找出最适合的传导理论。研究发现，在高电场条件下，空间电荷限制传导能够描述Al2O3中载流子的输运机制。估计的载流子迁移率似乎服从阿累尼乌斯定律，并且发现陷阱很浅。
The experimental electrical conduction current of Al2O3 has been investigated versus applied field (up to 40 kV mm−1) and temperature (from 293 to 403 K). Different conduction theories were confronted to experimental data in order to find the most suitable one. It was found that at high electric fields, space charge limited conduction is able to describe the carrier transport mechanism in Al2O3. Estimated charge carrier mobilities seem to obey an Arrhenius law and traps are found to be shallow.
