Acceptor Impurity
GaAs, at T=300  K, is uniformly doped with acceptor impurity atoms to a concentration of Na=2 ×10^16  cm^-3. Assume an excess carrier lifetime of 5 ×10^-7  s. (a) Determine the electron-hole recombination rate if the excess electron concentration is δn=5 ×10^14  cm^-3 ·(b) Using the results of part (a), what is the lifetime of holes? | Numerade
