Abstract
As beta increases in La2(-beta)Sr(beta)CuO(4), holes transfer from the cuprate-planes to the La-O layers-the opposite of what the charge-tra nsfer hypothesis predicts We interpret this analyzed charge-transfer a s indicating that the superconductivity originates in the vicinity of La-O layers, not in the cuprate-planes-contrary to previous interpreta tions of measurements which place the origin of superconductivity in t he cuprate-planes.
