| 中文摘要 | analysing the coordination state of copper ions in cuprate superconductors, it is found that the larger the energy splitting between d(x2-y2) and d(z2) orbitals of cu or the higher the energy of the d(x2-y2) orbital, the higher the tc. thus, appropriate coordination structures and strong-field ligands must be chosen for expanding the energy splitting and increasing the energy of the d(x2-y2) orbital when searching for new high-tc superconductors. summarizing the experimental results of esr and xps, it is considered that the [cu2+ - o open-square-box 2- - cu3+] resonance exists in cuprate superconductors and the electron field breathing mode is present. analysing the mechanism and the relationship between the coordination state of cu and tc, we consider that the two dimensional cu-o planes are responsible for the superconductivity of yba2cu3o7-y. |
