【摘要】 在研究高聚合电致发光二极管聚合物薄膜中的空穴(电子)的输运时,都忽略了一个这样的事实:在某些条件下,聚合物薄膜中的电场强度可能很高,这时,在强电场的作用下,高聚物链上可能会产生电子-空穴对,其中部分电子-空穴对可能会被离化,对电流作出贡献,本文根据Onsager理论,首先建立描述这部分电流产生的理论公式,然后进行计算,并与实验结果比较,与实验符合得很好。更多还原

【Abstract】 Under some specific condition. it might appear intensive electric field in polymeric thin film for polymericelectronluminescent light-mitting diodes. At that time beneath the function of intensive electric field, it may ariseelectron-hole pairs on polymer chain, and a part of electron-hole pairs could be ionized with contributing to electriccurrent. It was devoted to study this phenomenon in this paper. In the light of Onsager theory, the theoretical formulasfor describing the produce of this part of electric current was established at first, then the numerical calculation wasperformed, and the calculational values were compared with measured results at the end.更多还原
