Self consistent field (SCF) calculations carried out at San José State University (using MOLECOLE Linux codes) for a nano-particle of 18 molecules of T’-Nd2CuO4 explain the dxy symmetry for preferred superconductivity in the ab plane. These indicate that 1D conductivity is induced along the ab diagonal when there is a periodic lattice distortion (PLD) at site R: uexp(i(2pR.q+f)) (measured in X-ray diffraction (XRD)) of wave vector q and amplitude u. XRD and X-ray absorption (XAS) measurements were done (at the Stanford Synchrotron Radiation Laboratory (SSRL) and at the Lawrence Berkeley National Laboratory (LBNL-ALS)) on 50 nm c-axis oriented YBCO films (deposited on single crystal SrTiO3 and bi-crystals with a 24DEG grain boundary (GB) at the Complutense University). Understanding structure and distortions of YBCO films is important for device fabrication.
