Phys. Rev. Lett. 83, 392–395 (1999)Cuprate Superconductivity: Dependence of Tc on the c-Axis Layering StructureReceived 23 April 1998; published in the issue dated 12 July 1999 Without relying on any “model” of the in-plane behavior of the electrons in either the normal or the superconducting state, I show that for identically doped members of the same homologous series, as a result of the interplane Coulomb interaction, the difference ΔTc(n) of the transition temperature for the nth member from the single-layer value is given by ΔTc(n) = const×(1-1/n). On taking the constant from experiment, I predict large changes in the electron-energy-loss spectroscopy and optical properties in the midinfrared regime on entering the superconducting state, and further infer that the basic mechanism of superconductivity in the cuprates has a large contribution from the small- q regime. © 1999 The American Physical Society URL:
