2.45 It is possible to bring a low-doped germanium sam- ple to the state of n~ p = 10¹7 cm-³ in two ways: (a) by illumination at room temperature (b) by heating What are the quasi-Fermi level positions with respect to the midgap in each of these situations? Take the T3/2 temperature dependency of the effective density of states in both the conduction and the valence bands, and take the following room- temperature values: Nc = 1.0 x 1019 cm-3 and Nv = 6.0 × 1018 cm-3. Assume a constant energy gap of Eg = 0.66 eV.
