Their fractal dimension value D_f=1 .83. An in situdynamic observation of these films under TEM with slowly heating revealed that theinitial network fractal structure was damaged gradually and broken down completelyat 535℃. And as the annealing-induced aggregation developed, the random spreadaggregated gradually, the fractal dimension of the new structure decreased with theincreasing of annealing temperature. Finally, the D_f=1.63 at 850℃. Based on thesurface and interface diffusion model of the metallic atoms, the variation of thestructural character could be explained.
