A two-dimensional analysis of planar p-n-n+ junctions has been carried out using a successive-point overrelaxation method. This analysis gives better insight into the location of breakdown and the dependence of breakdown voltage on physical parameters of the junction, than obtained by a one-dimensional analysis. During the study an empirical relation has been found between breakdown voltage and the corresponding depletion-layer width. The computer program developed in this work enables calculation of generation current also. The information obtained helps in better device design.
