Abstract:	The relationship between superconductivity and hole concentration was studied in a series of tetragonal triple-perovskite La3−xCa2xBa3−xCu6Oy (0 ≤x ≤ 1.00) compounds. It was found that its superconductivity was dependent on the hole concentration of the Cu-O layers, but not on the hole concentration of the compound. It was semi-empirically demonstrated that superconductivity occurred in the Cu-O layers but not in the Cu-O chains in the La3−xCa2xBa3−xCu6 Oy compounds. Moreover, this explained the reason why La3Ba3Cu6Oy was not superconducting in terms of the degree of its hole concentration.
