摘要：

By comparing structural and superconducting properties of La2-x-yCaxNdyCuO4 to La2-xSrxCuO4 we have separated the effects of structure and doping on the superconducting T-c. At a fixed doping level, the highest T-c is found for flat and square CuO2 planes in the tetragonal structure. T-c is reduced by the structural distortions of the CuO2 planes in the orthorhombic structure. The local minimum of T-c vs doping observed around x similar to 0.12 indicates the presence of a weakly split singularity of the electronic density of states for the orthorhombic material.
