SUMMARY
The Fermi level in silicon is positioned at the center of the band gap for intrinsic (undoped) silicon, which has a band gap of 1.12 eV. Doping alters the Fermi level, shifting it towards either the valence band or the conduction band based on the type of dopant used. The equation E_f - E_i = kT ln(n/n_i) is essential for calculating the Fermi level, where E_f represents the Fermi energy and E_i is the intrinsic energy level. Understanding these concepts is crucial for applications in semiconductor physics and electronic engineering.
