GROWTH PHENOMENA OF BI2SR2CACU2O8-FILMS DEPOSITED ON (110)-ORIENTED SRTIO3 SUBSTRATES(DELTA THIN)

Thin films of Bi2Sr2CaCu2O8+delta have been deposited on (110) oriente d SrTiO3 substrates by inverted cylindrical magnetron sputtering. In s tructural studies, two competing growth orientations have been observe d: domains with the c-axis oriented perpendicular to the substrate sur face and inclined domains with the c-asis almost parallel to the [100] (S) and [010](S) directions of the substrate. For both growth orientat ions, in-plane alignment within the (110)(S) plane has been achieved. Domains of the different growth orientations are clearly reflected in the surface morphology of the films. (C) 1997 Elsevier Science S.A.
