The Monte Carlo simulation and experimental study are used to investigate the structure formation of Cu-Cr sandwiched condensates obtained by electron-beam evaporation. A 3-D model based on the assumption of a competitive growth of crystal grains from components having a bounded solid solubility is proposed. The crystal growth is described by a stochastic Poisson process where the probability for an atom to hit a crystal or a nucleus of crystallization is a function of the size and position of the crystal among other crystal grains. Calculations show that the assumptions proposed result in the self-maintained oscillations of condensation fluxes and the formation of sandwiched condensates, each film of which consists of a colony of nanosized columnar grains with the major axis directed along the condensation flux. In view of the modeled structures and the composition of crystallites, the results of calculations of the resistivity of layers are discussed.
