| Abstract: | Ten thousands of unit-cell multilayer heterosturctures, SrNb0.05Ti0.95O3/La0.9Sr0.1MnO3]3 (SNTO/LSMO), have been epitaxial grown on SrTiO3 (001) substrates by laser molecular beam epitaxy. The monitor of in-situ reflection high-energy electron diffraction demonstrates that the heterosturctures are layer-by-layer epitaxial growth. Atomic force microscope observation indicates that the surface of the heterosturcture is atomically smooth. The measurements of cross-sectional low magnification and high-resolution transmission electron microscopy as well as the corresponding selected area electron diffraction reveal that the interfaces are of perfect orientation, and the epitaxial crystalline structure shows the orientation relation of SNTO(001)//LSMO(001), and SNTO100]//LSMO100]. |
