Doping an insulator to make it a BCS-type superconductor, is equivalent to creating states in the Debye shell on both sides of the Fermi level. This doping is, therefore, equal to twice the product between the density of states at the Fermi level and the Debye energy. This formula works well for optimally doped cuprates suggesting a major role for phonons behind the superconductivity of these materials.
