摘要:
Electron backscatter diffraction (EBSD) was used for distinguishing crystallographic orientations and local lattice misfits of a La2Zr2O7 (LZO) buffer layer epitaxially grown on a cube textured Ni-5.%W (Ni-W) substrate for a YBCO superconductor film. Orientation data were obtained from the LZO epilayer using low energy primary electrons (5 key) and from the Ni-W substrate by increasing the voltage to 15 key. In-plane and out-of-plane orientations of the LZO epilayer were revealed with respect to its Ni-W substrate. A strong {1 0 0} < 0 1 1 > rotated-cube texture in the LW epilayer was formed on the {1 0 0} < 0 0 1 > cube-textured Ni-W substrates. LZO and Ni in-plane crystallographic axes are related by an expected 45 rotation. The step-misorientations and the local misfit strains between the LZO epilayer and the substrate were also analyzed.
