Abstract
Most previous studies of epitaxy have shown that growth of fee thin films on fee substrates leads to parallel, cube-on-cube orientation relationships. However, recent studies of Ag/Ni interfaces indicated that non-parallel orientation relationships may be preferred in fcc/fcc systems of large misfit. One objective of this study is to investigate the orientation relationships produced by epitaxy in Au/Cu bilayers. The Au/Cu system is especially interesting because it has complete mutual solid solubility despite the large lattice parameter misfit (∼ 12%). Hence, the second objective of this study is to investigate low-temperature interfacial diffusion phenomena in the special microstructures produced by multivariant epitaxy.
