Consider a p-type semiconductor at a temperature T(~300 K). Its bandgap Eg is 50 kpl. The ratio of the acceptor concentration (NA) and the intrinsic carrier concentration (Ni) NA/N; is e20. Assume that all the acceptors are ionized; the effective masses for electrons and holes are the same and known; and the energy at the top of the valence band is set as zero. Please do the following: a. Calculate E
b. Calculate EF
c. Find the N, in terms of N.
d. Find Ni in terms of N.
e. Find the electron concentration in terms of N.
