Karazin popup.description2 Object of studies is single and multi layer thin metal films. The aim of the project is to investigate the diffusion activity of multi-layer metal films versus their characteristic size and preparation conditions. The research methods. Films were obtained by means of vacuum condensation. The films structure was explored by high-energy electron diffraction, transmission electron microscopy, X-Ray diffraction methods and Auger electron spectroscopy. It has been shown that the under vacancy mechanism the surface and bulk dif-fusion coefficients increase of many orders of magnitude with reducing of the small particles sizes. Is has been found the formation of alloy in Cu-Au film sys-tem obtained by sequential deposition of components on the substrate at room temperature. The main results are received for the first time. Their actuality is stipulated both by fundamental nanophysics needs and wide usage of nanosized objects in modern technologies. Product Description popup.authors popup.nrat_date 2020-04-02 Close
