A GaAs sample with nn0 = 10^16 cm-3 is illuminated with light and 10^13 electron-hole pair/cm3 are created every microsecond. The mean scattering times are tm = tp = 2 ns. a. Find the majority and minority carrier concentrations before and after illumination. b. Find the quasi-Fermi levels at room temperature and plot flat energy band diagram. c. Calculate the value of pn before and after illumination. A GaAs sample with nn0 = 10^16 cm-3 is illuminated with light and 10^13 electron-hole pair/cm3 are created every microsecond.
