| 内容記述 | In order to explore the reason why the single-layered cuprates, La2−x(Sr/Ba)xCuO4 (Tc≃40 K) and HgBa2CuO4+δ (Tc≃90 K) have such a significant difference in Tc, we study a two-orbital model that incorporates the dz2 orbital on top of the dx2−y2 orbital. It is found, with the fluctuation exchange approximation, that the dz2 orbital contribution to the Fermi surface, which is stronger in the La system, works against d-wave superconductivity, thereby dominating over the effect of the Fermi surface shape. The result resolves the long-standing contradiction between the theoretical results on Hubbard-type models and the experimental material dependence of Tc in the cuprates. | |||||
