A 27 g sample of germanium crystal contains 44 mg of arsenic. The arsenic is substitutionally incorporated into the crystal. Germanium has a band gap of 0.66 eV and an intrinsic carrier concentration at 25o C of 4.2e+13 cm-3. At what temperature (in oC) will the intrinsic carrier concentration equal the extrinsic carrier concentration?
