Popis:	We address room-temperature conductivities of chemically grown silver films. Disordered, granular silver films are grown using a modified Tollens reaction. Thick, polycrystalline films are transparent at visible wavelengths, with crystallinity similar to that of silver powders. The measured conductivities are close to those measured by I. V. Antonets, L. N. Kotov, S. V. Nekipelov, and Ye. A. Golubev, Tech. Phys. 49, 306 (2004) in amorphous silver films, however the thickness where bulk conductivity is reached is anomalously high. While measured resistance values do not obey a scaling relation in thickness, accounting for the films’ structural porosity through geometrical rescaling of the thickness leads to emergence of the well-known percolation power-law scaling, albeit that of two-dimensional percolating films.
