Alternative way for numerical steady-state analysis of forward-biased p-n junction devices

At large forward bias, quasineutrality holds in all regions of p-n devices. As a consequence, accurate numerical solutions of the transport equations can be obtained without involving the treatment of Poisson´s equation. A new approach is thus proposed which avoids convergence problems and excessive computation time in numerical studies of forward characteristics of p-n devices, rectifiers and thyristors.
