An abrupt pn junction of the type of has been doped with NA 5 1016/cm3 and ND 5 1018/cm3 . (a) Find the voltage v needed to make Xd 5 1 m. Hint: exploit the fact that ND @ NA. (b) Sketch and label, versus x, the resulting potential (x); assume (x $ xn) 5 n. (c) Find the cross-sectional square area needed to achieve Cj 5 1 pF at the voltage of part (a).
