Abstract

We have fabricated multilayer p-n hetero-junction structure La _0.9Sr_0.1MnO₃/SrNb_0.05Ti _0.95O₃ colossal magneto-resistivity thin films. The observations of transmission electron microscopy showed that the interfacial structure between La_0.9Sr_0.1MnO₃ and SrNb _0.05Ti_0.95O₃ was of great epitaxy and atomic level smooth. There was a superstructure within La_0.9Sr _0.1MnO₃ thin films which was clarified in terms of the ordered partial substitution of La with Sr at center body of unit cell. Its chemical composition and distribution information investigated by electron energy loss spectrum and element mapping in the multilayer thin films were discussed.
