The epitaxial growth of Bi2Sr2CaCu2Ox (Bi2212) high
temperature
superconducting thin films was studied. The films were solution-deposited
from a polymer-containing precursor onto SrTiO3 (001) substrates.
Bi2212 formed an epitaxial phase with the c-axis parallel to the
substrate normal and an in-plane orientation with the a-axis parallel to
the SrTiO3 [110] and [ 
10] directions. This phase was found to be robust
with respect to small
changes in stoichiometry, where the appearance of an additional
BiSrCuO phase was observed. This minority phase
had no major effect on the epitaxial alignment of the Bi2212 phase or the
critical temperature of the thin-film sample.
