“…The impact of nucleation exclusion zones on the randomness of the spatial distribution of nuclei has been observed in various works to be reflected by the distribution of the nearest-neighbor (NN) distances and the radial distribution function (RDF) of the nuclei [8][9][10][11][12]. Experimental results show that the degree of inhomogeneity could be influenced by the deposition overpotentials [9] and the supporting electrolyte [13]; increasing the overpotential reduces the NN distances and undermines the randomness of the nuclei, while the addition of a supporting electrolyte will improve the spatial randomness of the nuclei.…”

In this work, the nearest-neighbor distances and Voronoi cell features of Cu-Ag deposits were analyzed and fitted with Lognormal, Weibull, and Gamma distributions. The nearest-neighbor distance distributions of the samples were compared with those of complete spatially random points, showing spatial inhomogeneity due to the nucleation exclusion effect. The radial distribution function was calculated, showing both influences from the grain size and the nucleation exclusion effect. Voronoi cells were generated based on the shape of the grains. The size, occupancy, and coordination of the Voronoi cells were examined and fitted. The results show that although the Cu-Ag deposits seemed to be governed by the instantaneous nucleation mode, the spatial distribution of the nuclei was more impacted by the nucleation exclusion effect than the Cu-only samples. This behavior is also justified by the grain size distribution generated with Voronoi cell size and occupancy distributions.

“…The purpose of this study is to apply a new approach to the quantitative description of spatial distribution of copper particles on glassy carbon (GC) surface. Double pulse technique was used for electrodeposition of copper crystallization centers on polished GC from sulfate electrolyte [4]. Spatial distributions of copper particles on GC were analyzed using statistical methods.…”
