Electron Microscopy of Au/Ni Artificial Superlattice Films

H. Dohnomae*, N. Nakayama* and T. Shinjo*

Cross-sections of Au/Ni multilayered films with artificial superstructures have been observed by a transmission electron microscope. Images have revealed alternate coherent stacking of [111] oriented fcc Au and Ni layers. Electron diffraction patterns indicate that films have fiber texture structures. In-plane coherent grain sizes are less than 10 nm. The surface morphology is dependent on the artificial period; films with shorter periods have smoother surfaces. Interface roughness in the range of 3-4 lattice planes causes columnar structures for the multilayered films with longer periods.
