The influence of annealing process on the structure of ultrathin gold films on the surfaces of glass substrates and substrates of CdS is investigated. The formation of nanoparticle arrays as a result of annealing the films on the glass surface was revealed, and analysis of average radii dependence for the formed particles on initial thickness of the film was carried out and shape of the particles analyzed. For annealed Au films on the surface of CdS, the destruction of the film for its initial thickness of 0.5 and 1 nm was noted, and small changes in the surface morphology for thicker films were observed. On the basis of elemental analysis, assumptions about the causes of such temperature behavior of films are made.
