Abstract: | The Atomic Kinetic Lattice Monte Carlo method was used to model the effects of a clustering impurity species on the deposition
of nanocrystalline nickel films onto (001) copper. The deposition model was partly parameterized by physical inputs from atomistic
calculations of copper-nickel alloys. The grain size and shape is shown to depend on the concentration of impurities in the
deposited film. Low concentrations yield elongated columnar grains, while higher concentrations produce much smaller and more
equiaxed grains.
