18.26 (a) In your own words, explain how donor impurities in semiconductors give rise
to free electrons in numbers in excesS of those generated by valence band-conduction band
excitations. (b) Also explain how acceptor impurities give rise to holes in numbers in excess of
those generated by valence band conduction band excitations.

A region of N-type semiconductor doped by Nd=10^15 cm^-3 is fully depleted of both majority and minority carriers by an external electric field. Assuming that the concentration of electron-hole pairs that is generated per unit time does not change when the semiconductor is depleted, determine the effective generation rate if the semiconductor is (a) Si (ni = 1.02 × 1010 cm-3) and (b) GaAs (ni = 2.1 × 106 cm-3). The minority-carrier lifetime is 1 μs in both cases.
