Fantastic news! We've Found the answer you've been seeking!
Question:
assume that the hole concentration is not significantly affected by optical pumping and thus the quasi Fermi level for holes, Fp, is degenerate with the valence band edge, i.e. Fp = Ey. Calculate the minimum photo-generated electron concentration (in cm 3) for net stimulated emission. Hint: You cannot use non-degenerate semiconductor approximation. Instead, you must use the full Fermi-Dirac function in your calculation. Answers within 5% error will be considered correct.
