An n-type Si sample with Na = 105 cm3 is steadily illuminated

such that Sop = 10 EHP/cm-s. If T = Tp = 1

An n-type Si sample with Na = 105 cm3 is steadily illuminated such that Sop = 10 EHP/cm-s. If T = Tp = 1 us for this excitation, calculate the sepa- ration in the quasi-Fermi levels, (F Fp). Draw a band diagram such as Fig. 411. - n 0.233 eV 0.186 eV Ec -F EF Fp Ei Ev Figure 4-11 Quasi-Fermi levels F and F, for a Si sample with no = 104 cm-3 Tp = 2 s, and gop = 101 EHP/cm-s (Example 4-4).
