C. Peter Flynn Bonham, Scott William 2015-09-25T20:03:25Z 2015-09-25T20:03:25Z 10000-01-01 1997 1997 During epitaxial growth of (111) face-centered cubic crystal films, such as disordered $\rm Cu\sb3Au,$ there are two possible ways that successive layers can be laid down, leading to two types of stacking domains. However, a small vicinal miscut $(0.5\sp\circ {-}1\sp\circ )$ of the crystal surface introduces step edges that change nucleation preferences of the domains, resulting in one being preferred over the other by ratios up to 700:1. Fifteen samples were measured and this preference has been found to depend systematically and strongly on the magnitude and direction of the sample miscut. A qualitative RHEED study confirms that a preference for one of the stacking senses is present after deposition of a few monlolayers of $\rm Cu\sb3Au.$ The observed behavior of the film can be explained by a model in which Cu and Au atoms minimize their number of Nb nearest neighbors when growing over the Nb step edges. This represents both a discovery of a new phenomena in epitaxial nucleation and a technique for the production of improved epitaxial films. Made available in DSpace on 2015-09-25T20:03:25Z (GMT).
