Sn1-x/Six cluster assembled films were prepared using a plasma-gas-condensation cluster beam deposition apparatus by energetic cluster impact deposition, and their conductivities were measured for various compositional ratios and packing fractions f. We found that the electrical conductivity σ of Sn1-x/Six cluster assembled films obeys a power law of the Sn concentration pSn. The marked change at approximately pSn = pc, indicates that the percolation of Sn clusters takes place at the threshold value pc. Moreover, we successfully demonstrated using Sn1-x/Six cluster assembled films with various f values that the critical volume fractions of a percolating object, υc = fpc, can be invariant with respect to f.
