ABSTRACT

We investigated pattern formation in Ag-In electrodeposition by constructing a morphology diagram that indicates the presence of pattern at a current density and cathode potential. The patterns that emerge as a fishbone and tree are found to have a fractal property. As the current density increases, the fishbone-like pattern with a fractal dimension of 1.44 changes into the tree-like pattern with a fractal dimension of 1.64. The increase in the fractal dimension is related to an increase in the number of branch in the pattern.
