All the books that deal with the p-n junction under applied bias asume that the same equations used for the equilibrium case (no bias) can be used for the biased case provided that the juntcion voltage [itex]V_{ic}[/itex] is substituted by [itex]V_{ic}-V[/itex], where [itex]V[/itex] is the applied bias. Although this can seem plausible I don't see any reason for why the junction voltage drop should be the [itex]V_{ic}-V[/itex], i.e., why the voltajes should obey a sort of superposition principle.
Is there any reason on the ground of fundamental electrostatic / thermodynamics?
Thanks.
