Variation of Superconducting Transition Temperature in Hole-Doped Copper-Oxides

Abstract

The experimentally observed difference of superconducting critical temperature $T_c$ in hole-doped cuprates is studied by using an extended interlayer coupling model for layered d-wave superconductors. We show that the change of the maximum $T_c$ from series to series is determined by the next nearest neighboring hopping $t^{\prime }$, while the difference of the maximum $T_c$ among the compounds in a homogeneous series is controlled by the interlayer pairing strength. Our results provide helpful guidelines in the search for new high-$T_c$ superconductors.
