Annotation The results of electron microscopic studies of arrays of nanoparticles formed by melting of solid polycrystalline Bi films on amorphous Ge and SiO2 substrates are presented. It has been shown that the islet structure with a small spread of particle’ size has formed as a result of self-organization during the melting of bismuth on an inert SiO2 substrate. The connection between the basic characteristics of these particles and the thickness of the initial films were determined. It has been shown that melting of bismuth on the amorphous germanium substrate leads to formation of disordered arrays of nanoparticles. The morphological structure of these ones depends on the nature of interaction between the components of the film-substrate interface.
