Formation of Bi2212 Phase via Bi2201 Phase in Liquid-Phase Epitaxial Growth

Bi2212 single-phase films are prepared using the liquid-phase epitaxial (LPE) method. The dependence of the relative content of the Bi2212 phase in the as-grown films on the growth temperature has made it clear that the Bi2212 phase can be obtained in a narrow temperature region around 980°C. LPE growth under the liquid-temperature gradient is examined. It is found that the temperature gradient suppresses the growth of the Bi2212 phase.
