Al. Vasiliev et al., SINGLE VARIANT ORIENTATIONAL GROWTH OF YBA2CU3O7-X ON VICINAL(011) SRTIO3 SUBSTRATES OBSERVED BY ELECTRON-MICROSCOPY, Physica. C, Superconductivity, 289(3-4), 1997, pp. 243-250
The results of a transmission electron microscopy (TEM) and X-ray micr
oanalysis (EDS) study of YBa2Cu3O7-x (YBCO) films grown on vicinal(011
) SrTiO3 substrates are presented. The YBCO films tend to be single cr
ystalline grown in single variant orientation with c-axis approximate
to 45 degrees from the surface. Cracks, second phase precipitates (CuO
and Y2O3), and a few small YBCO grains in other orientations were rev
ealed in the films. (C) 1997 Elsevier Science B.V.
