Conductivity features of nanoislet metal films

Structural percolation transitions in ultrathin metal films at thermally activated granularity was studied. The degree of granularity of an Au/GGG film is shown to increase with decreasing its effective thickness. The film structure peculiarities are visualized upon the percolation transition via scanning electron microscopy. The feasible causes, mechanisms and models of activation conductivity in islet metal nanofilms are discussed and the statistical width distribution of inter-islet gaps is considered, as well.
