Abstract
Polarized X-ray absorption measurements reveal that photodoping of oxygen deficient YBa2Cu3O6+x (YBCO) produces a local axial distortion of the CuOx chains. The broad normal state axial Cu(1)-O(4) bond distribution becomes two well-defined peaks in the photodoped state and suggest local ordering. XANES measurements reveal a transfer of hole density into the CuO2 planes. These results support a common structure-related transport enhancement mechanism in chemically doped and photodoped high temperature superconductor systems. © 1997 Elsevier Science B.V.
