In class we will often use Boltzmann statistics in place of FermiDirac statistics since the
Boitzmann distribution function is much simpler than the Fermi-Dirac distribution. The
purpose of this homework is to gain an understanding of the limits of this a

0.239eV respectively in the emitter, base, and collector. Also, with N AE > NDB, the
EB depletion width will lie almost exclusively in the base. Likewise, the majori
