【摘要】 利用价电子轨道能量Ei和价电子层数ni,构建了新的原子点价δi,由点价δi构建价电子轨道能量拓扑指数mE。研究了Y系、Bi系高温超导氧化物与mE的0阶指数的关系,发现有较好的规律性。因此文中提出用价电子轨道能量拓扑指数mE作为Y系、Bi系高温超导氧化物超导电性的一个新判据,对今后制备出具有更高TC的Y系、Bi系超导氧化物有很好的指导意义。更多还原

【Abstract】 Using the valence electron orbit energy(Ei) and number of valence electron shell(ni),a new connectivity topological index(mE) was proposed from δi.Studying the relation of the 0 order of index with Y series、Bi series oxide superconductors,an empirical rule is found.It is suggested that the Topological Index mE of Valence Electron orbit energy can be used as a empirical criterion for the superconductivity of Y series、Bi series oxide superconductors.It has a good instruction significance to the researchers on synthesizing Y series、Bi series oxide superconductors of the higher Tc.更多还原
