In this paper the results of modeling of the growth of island thin film by using a diffusion model of growth and theoretical investigation of its electrical conductivity in the approximation of the Sommerfeld-Bethe-Hill were presented. With increasing in the sticking probability of the particles forming more branched fractal structure, and with a decrease in the sticking probability moving particle can diffuse deeper into the fractal structure that allows you to simulate islands «round» shape. Current-voltage characteristic for low voltages is linear. The tunneling currents dominate at low temperatures and small gaps, the thermionic emission dominates at elevated temperatures in the region of large gaps. The simulation allows a qualitative assessment of the nature and conditions of the preparation of thin nanofilms with predetermined morphological properties and assess their conductive properties.
