作者考虑到聚合物的形态结构和能带特点,应用近似的平板能带理论,说明了电子和空穴注入的不同方式和途径。同极性空间电荷的形成过程中存在着两种相互矛盾的作用,一方面它降低针尖附近介质中的电场强度,有提高树枝起始电压的趋势;另一方面注入过程中正负载流子的复合或热电子的作用,有降低树枝起始电压的倾向。模型中首次提出了在聚合物的树枝潜伏期内存在着一个低密度区的过渡阶段,并用条纹图象法证明了这个区域的存在。其他一些特殊试验支持了新模型的构思。
Taking into account the morphological and energy bandgap characteristics of the polymer, the authors apply an approximation of the plate energy band theory, illustrating different ways and approaches for electron and hole injection. There are two contradictory roles in the formation of the space charge with the same polarity. On the one hand, it reduces the electric field strength in the medium near the tip and increases the initial voltage of the branch. On the other hand, the recombination of positive and negative charge carriers Or hot electron effect, there is a tendency to lower the threshold voltage of the branch. For the first time in the model, there was a transitional period of low density region in the polymer’s tree branch latency and the existence of this region was proved by the stripe image method. Other special experiments support the idea of a new model.
