Tc vs n relationship for multilayered High-Tc superconductors

We have proposed a T-c vs n relationship for multilayered high-T-c superconductors from the analysis of HgBa2Can-1CunOy grain-aligned samples containing n = 6 to 16 phases. The sample showed a large and sharp superconducting transition at 105 K in its susceptibility vs temperature curve. This means that multilayered HgBa2Can-1CunOy can maintain a high T-c at least up to n approximate to 16, otherwise many transitions would have been observed. It is generally believed that the highest T-c decreases with n for n >= 4-5 for multilayered superconductors. We conclude that the highest T-c is almost constant above about n = 5 if the factors reducing T-c such as disorder, are eliminated for multilayered superconductors. This behavior can be explained using an inhomogeneous charge distribution model in multilayered cuprates.
