What this tells you is E In particular,if you have an empty region of space or a region 0 where nothing has electrical charge then E has divergence equal to zero.
Experiment results show that the application of an electric field causes nonuniform distribution of the density of the defects in the spacechargeregion.
实验结果表明,辐照电场的存在将造成缺陷在空间电荷区的不均匀分布。

With sufficient forward bias, the diffusion capacitance can easily exceed the spacechargeregion capacitance.
