Webd-wave symmetry for the superconducting gap. These observations imply that the superconducting order in this electron-doped cuprate can be well described in terms of a disordered BCS d-wave formalism. WebThe BCS theory is based on a weak coupling approximation, i.e., the electron–phonon coupling constant λ ≪ 1 at T = 0. Here, λ reflects the strength of the electron–lattice interaction. However, for many superconductors, λ ≥ 1. For example, λ = 1.4 for lead, λ = 1.6 for mercury, and λ = 2.1 for P b 0.65 B i 0.35.
