Theory/experiments of X-Ray flux effect on periodic lattice distortions in YBCO

Sahibudeen H.S., Navacerrada M.A., Acrivos J.V., San Jose State University, US

The dynamics for the effect of X-ray flux on periodic lattice distortion waves in YBCO (YBa2Cu3O7-d) 50nm films on STO *SrTiO3) is described: The X-ray flux r(t)=photons/s can induce many possible resonant excitations between states, [...]

Theory and Experiments on Periodic Lattice Distortions that Explain 1D Conductivity along the CuO2 Plane Ab And A-B Diagonals in YBa2Cu3O7 (YBCO) 50 nm Film with a 24 DEG Grain Boundary (Gb)

Sahibudeen H.S., Navacerrada M.A., Acrivos J.V., San Jose State University, US

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. [...]

Periodic Lattice Distortion in YBa2Cu3O7 50 nm film on SrTiO3

Navacerrada M.A., Acrivos J.V., San Jose State University, US

Synchrotron X-ray diffraction has been used to detect novel periodic lattice distortions (PLD) in highly c-axis oriented YBa2Cu3O7 (YBCO) 50 nm films grown on SrTiO3 substrate. The growth layer by layer of 50 nm YBCO, [...]
