Derive expressions for concentrations of free carriers in a semiconductor doped with both, donor and acceptor impurities.

Question:

Derive expressions for concentrations of free carriers in a semiconductor doped with both, donor and acceptor impurities. Determine the conductivity type and calculate the concentrations of carriers in silicon at T = 300 K, if it is doped with:

(a) N_A =1016 cm-3> > N_D.

(b) N_D = 1016 cm-3> > N_A.

Assume that all impurities are ionized and ni = 1.38 × 10¹⁰ cm^-3 at 300 K.
