✦ Synopsis

Fractal structures were observed in discontinuous Cu films evaporated onto quartz-glass substrates in vacua (IO-' Torr). On the basis of electron micrographs, the coverage coefficients, fractal dimensions D and correlation lengths c were determined for the Cu films with coverage coefficients p ranging from 0.3 to 1. The correlation function method was used to determine the fractal dimensions for the experimental, as well as

for the computer modelled films. In the percolation range some critical exponents f/I?, v) were determined. The results were compared with the values theoretically predicted, and with the results previously obtained.
