Abstract: We use resonant soft x-ray scattering RSXS to quantify the holedistribution in a superlattice of insulating La2CuO4 LCO and overdopedLa {2-x}Sr {x}CuO4 LSCO. Despite its non-superconducting constituents, thisstructure is superconducting with T {c}=38 K. We found that the conductingholes redistribute electronically from LSCO to the LCO layers. The LCO layerswere found to be optimally doped, suggesting they are the main drivers ofsuperconductivity. Our results demonstrate the utility of RSXS for separatingelectronic from structural effects at oxide interfaces.
