Electrical conductivity of conductive films based on random metallic nanowire networks

Using computer simulation, we investigated the dependence of the electrical conductivity of random two-dimensional systems of straight nanowires on the main parameters. Both the resistance of the conductors and the resistance of the contacts between them were taken into account. The dependence of the resistance, $R$, between network nodes on the distance between nodes, $r$, is $R(r)=R_{\mathrm{\square }}\mathrm{/}\pi \ln r+\mathrm{c}\mathrm{o}\mathrm{n}\mathrm{s}\mathrm{t}$, where $R_{\mathrm{\square }}$ is the sheet resistance.
