· Physical Review Letters
By calculation and analysis of the bare conduction bands in a large number of hole-doped high-temperature superconductors, we have identified the range of the intralayer hopping as the essential, material-dependent parameter. It is controlled by the energy of the axial orbital, a hybrid between Cu4s , apical-oxygen 2p{sub z} , and farther orbitals. Materials with higher {Tc}{sub max} have larger hopping ranges and axial orbitals more localized in the CuO{sub 2} layers.
