The growth of ultrathin Au films on Ni{1 1 1}
Abstract
<p>The initial growth of Au on Ni{1 1 1} is strongly influenced by the 15.7% difference in bulk lattice parameter between the two fcc metals. At 400 K, the first monolayer of Au grows on the Ni{1 1 1} surface as a (9 × 9) overlayer with 8 Au-Au spacings being equivalent to 9 Ni-Ni spacings. Umezawa et al. [Physical Review B 57 (1998) 8842; Surface Science 426 (1999) 225] reported that the growth of Au overlayers can occur either via a reverse (R)-mode (i.e., incorporating a stacking fault at the Au-Ni interface) or a normal (N)-mode-the relative proportion of each mode being strongly sensitive to growth temperature. Using the technique of medium energy ion scattering, we examine the growth of Au on Ni{1 1 1} at 400 K. We conclude that, at this deposition temperature, there is a preference for growth via the R-mode (74 ± 9%). In addition, we find that the Au overlayer has a considerably higher density than bulk Au being contracted isotropically by 3.1% in the {1 1 1} plane and also by ∼7% perpendicular to the {1 1 1} plane. We discuss possible explanations for our findings.</p>
