We have derived the current-voltage relationship of ideal p-n junctions. One of the assumptions was that the quasi Fermi levels are constant across the depletion region. However this is contradictory to the requirement that there is a (constant) current across the depletion region
a. Write explicit expression for Jn and Jp in only terms of carrier density, mobility, and Quasi Fermi Level (derivative of QFL)b. Compute the gradient(derivative) of the Electron and Hole QFL for a pn diode with Nd=2x1016 and Na=1x1017 cm-3, use mobilities for silicon and assume the current density is 103 A/cm2.c. Compute the width of the depletion region.d. Determine the potential drop across the depletion region and thus explain why it is appropriate to make the assumption that the quasi Fermi levels are constant across the depletion region.
