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.
