Transition region properties of reverse-biased diffused p-n junctions

Poisson´s equation is solved for two common types of diffused p-n junctions in a manner similar to that of previous authors. By a suitable transformation, the field in the junction and capacitance-voltage relation for all junctions are shown to be presentable as a single family of curves with no approximation other than the assumption of negligible drift field. The abrupt and graded regions are discussed in detail. The zero-bias potential and capacitance are also discussed.
