Consider a pn+ junction with doping NA = 1016 and ND = 1018 cm−3 at a forward bias of 0.4 V.

(a) Calculate the excess carrier distribution δn(xp) and δ(xn). Which one is largest?

(b) Draw the excess carrier distribution.

(c) At what voltage is the carrier injection starting to reach high level? (i.e. ∼ 10% of majority level)
