The main theoretical models of the classical size effect in thin metal films are analysed. A new model of charge transport in a thin polycrystalline film is suggested. It is assumed that a polycrystalline film consists of the grains which are situated in the layer with a heterogeneous cross–section. The amplitude of surface macroscopic roughness is commensurable with the average grains radius. The development of this model allowed us not only to describe the surface and grain–boundary scattering of charge carriers in polycrystalline films, but also to estimate the middle value of surface roughness parameter. The derived theoretical expressions were used to explain the experimental data.
