摘要

We report measurements of both the normal-grate reflectance and the superconducting- to normal-state reflectance ratio of a thin film sample of Tl2Ba2CaCu2O8 at near-normal incidence for photon energies between 0.09 and 4.5eV. From these data we have obtained the real part of the superconducting- to normal-state optical conductivity ratio, Re(sigma (S)/sigma (N)). This quantity can be related directly to structure in Delta(omega) without the need to invoke Eliashberg theory. We find structure in Delta(omega) for superconducting Tl2Ba2CaCu2O8 at low-energy, presumably due to electron-phonon coupling, and additional structure at approximately 1.2eV and 1.7eV which we attribute to an electronic component of the pairing interaction in this material.
