Abstract: | Cu3Au films are grown under a number of conditions, which isolates step nucleation as the key to the stacking bias. The stacking ratio has a sinusoidal dependance on miscut azimuth. The ratio depends on miscut magnitude first linearly but with a rapid increase for miscuts; near 1°. This behavior fits well with a model of selective step nucleation for adatoms within diffusion distance of surface steps. Variations in average adatom chemistry and size have little effect, leaving the best explanation for stacking selection as an adatom affinity for step nucleation due to increased coordination number and reduced energy at step sites. |
