Asi sample with 1016 cm-3 donors is optically excited such that 1019 cm-3 electron/hole pairs are generated per second uniformly in the sample. the light causes the sample temperature to rise to 450 k. find the quasi-fermi levels upon shining the light on the sample. electron and hole lifetimes are both 10 μs. dp = 12 cm2/s, dn = 36 cm2/s, ni = 1014 cm-3 at 450 k.
