The electron–phonon mechanism of superconducting pairing in the two-band Emery model on a square lattice is considered. On the basis of the equation of motion the self-consistent system of equations for the matrix electron Green function is obtained. The dependence of the superconducting transition temperature T c on the concentration of holes is calculated. It is shown that due to the exclusion of double occupancy of copper sites the maximum T c occurs at the concentrations of holes n ≈ 0.8 and n ≈ 2.3, which correspond to the Van Hove singularities in copper and oxygen band, respectively.
