WebThis derivation is based on solving the Poisson equation in one dimension – the dimension normal to the metallurgical junction. The electric field is zero outside of the depletion width (seen in above figure) and therefore Gauss's law implies that the charge density in each region balance – as shown by the first equation in this sub-section. http://optique-ingenieur.org/en/courses/OPI_ang_M05_C02/co/Contenu_05.html
