The results of research devoted to formation of ordered arrays of particles during melting process of tin films on amorphous carbon substrate are given in the present work. Using scanning electron microscopy the histograms of particle size distribution are constructed for films of different mass thickness. The size dependences of the most probable radius of particles, which are formed during the melting process, and the half-width values of the corresponding histograms are obtained as well. The excess energy, which provides a decomposition of the initially continuous film into separate islands, is estimated and its size dependence is built. As shown, the melting process of films, which are condensed in island structures, provides larger filling coefficients in comparison with the melting process of initially continuous films.
Key words: annealing of films, thermal decomposition, histogram and half-width of distribution, excess energy.
