Stroganov O. The effect of germanium underlayers on the structure and charge transport phenomena in thin copper, gold and silver films.

The preparation possibility of polycrystalline metal gold, copper and silver films with the desired structure, predicted electrical conductivity and optical parameters in ultrahigh vacuum were presented in the work. The mean linear dimensions of the film crystallites sizes were made by use of both "quench condensation" method of thermally evaporated metal with surfactant germanium underlayers, under stabilization temperature at first temperature zone (T1 ≤ 0,3Тm.) of the reconstructed model of the Movchan-Demchishin structural zones. The correlation between film structure (average linear dimensions of the crystallites) and percolation threshold dc were experimentally established.Base on complex experimental investigation of size dependences of optical percolation film thickness, dynamic electrical film conductivity, spectral dependences of transmission, reflection and absorption coefficients were explained in the framework of percolation theory.
