Ionized dopants and quasi-fermi level

  1. Sep 22, 2010 #1
    Hello all,

    I have a question regarding quasi-fermi levels that probably some one can help me to understand.

    In a pn junction in equilibrium we can calculate the number of ionized dopants from the distance between the ionization energy of the dopants and the fermi level.

    Now, if we apply a voltage, we can in general define two different quasi-fermi level for holes and electrons. How can we calculate the number of ionized dopants now?

    Thanks for any help,
