Formation of Bi2212 phase via Bi2201 phase in liquid-phase epitaxial growth

Bi2212 single-phase films are prepared using the liquid-phase epitaxial (LP E) method. The dependence of the relative content of the Bi2212 phase in th e as-grown films on the growth temperature has made it clear that the Bi221 2 phase can be obtained in a narrow temperature region around 980 degrees C . LPE growth under the liquid-temperature gradient is examined. It is found that the temperature gradient suppresses tho growth of the Bi2212 phase.
