Structure, DC electrical conductivity, and optical properties of thin silver films quench prepared under ultrahigh vacuum conditions on the surface of the bare glass and the glass precoated with germanium sublayers with a mass thickness of 0.5 nm are studied. Ultrathin films of germanium sublayers accelerate the metallization of a silver film by reducing the average linear dimensions of crystallites in the condensed layer of metal vapour that manifests itself in a decrease in the threshold thickness of the percolation transition. The $d_{\textrm{c}}$ thicknesses of metal films, which correspond to the percolation transition and are determined by measurements of DC electrical conductivity and optical transmission of films in the wavelength range $\lambda$ = 300–2500 nm, agree well with each other.

Key words: thin metal films, sublayers of subatomic thickness, percolation, electroconductivity, reflection coefficient of films.
