On the basis of Wirth-Rogers photocurrent models, the enhanced models include two additional effects as high injection effects on excess minority carrier lifetime and electric fields in the substrate ( quasi-neutral regions). These effects are most pronounced in high resistivity material. 该模型在Wirth-Rogers光电流模型的基础上,增加考虑了高注入对过剩载流子寿命的影响以及衬底(准中性区)电场的效应,这些效应对于高阻材料是不容忽视的。
In this paper, the condition under which the surface excess minority carrier density may be treated as a constant is also analysed. 在文中,我们也分析了可以把表面非平衡少子浓度作常数处理的条件。
