Abstract
The Madelung energy of La2-xCa1+xCu2O6 system, whose properties change from semiconductor to superconductor under high-oxygen-pressure annealing, is calculated. We find the increase in VA, the difference in Madelung site potential between the apex and the CuO2 planes oxygen, promotes the superconducting transition in this system. Slight intercalation of oxygen between two CuO2 planes is found to be of primary importance in determining VA.
