Metallic thin film growth on vicinal Cu substrates
چکیده انگلیسی

In this study we have investigated the heteroepitaxial growth of nickel and silver on vicinal copper substrates. Nickel was deposited onto a (211) substrate. The low lattice mismatch between copper and nickel of 2.5% enables epitaxial bidimensional growth in the substrate's orientation, where the strain can be accommodated in the overlaying film. On the contrary, copper and silver have a much larger mismatch of about 13% which usually cannot be accommodated in the film. In general, Ag is known to form alloys or to induce faceting on a stepped Cu surfaces. Here, silver was deposited onto a Cu(311) facet covered with a monatomic layer of NaCl. For the first time we show that Ag can be grown as ultrathin film in the substrates's orientation on a stepped surface using NaCl as a novel surfactant material.
