Doping introduces additional electron energy levels into the band gap, that may or may not be populated by electrons, dependent on circumstances and temperature, and causes the Fermi level E < sub > F </ sub > to shift from the energy level ( relative to the band structure ) that it would have had in the absence of doping.
