| 内容記述 | We study superconducting transition temperature (T_c) of oxygen-doped double-layer high-temperature superconductors YBa_2Cu_3O<6+δ> (0≤δ≤1) as a function of the oxygen dopant concentration (δ) and planar hole-doping concentration (P_<pl>). We find that T_c, while clearly influenced by the development of the chain ordering as seen in the T_c vs plot, lies on a universal curve originating at the critical hole concentration (P_c)=1/16 in the T_c vs P_<pl> plot. Our analysis suggests that the universal behavior of T_c(P_<pl>) can be understood in terms of the competition and collaboration of chemical phases and electronic phases that exist in the system. We conclude that the global superconductivity behavior of Yba_2Cu_3O<6+δ> as a function of doping is electronically driven and dictated by pristine electronic phases at magic doping numbers that follow the hierarchical order based on P_c, such as 2×P_c, 3×P_c, and 4×P_c. We find that there are at least two intrinsic electronic superconducting phases of T_c=60 K at 2×P_c=1/8 and T_c=90 K at 3×P_c=3/16. | |||||||||||
