Galuza O. Analysis, synthesis and diagnostics of complicated radiation-induced and multilayer systems on the surface of solids

Object: the complex radiation-induced formations and multilayered systems on a surface of solid bodies. The purpose: creation of the complex not destroying approach to the analysis, synthesis and diagnostics of difficult, in particular, multilayered thin-film structures on surfaces of solid bodies, studying of influence of radiating factors on physical properties of blankets of solid bodies. Methods: ellipsometry, reflectometry, interferrometry, optical microscopy, the Ozhe-analysis, mass spectroscopy and electronic microscopy, optimization and the mathematical statistics. Results: for the first time the complex of quantitative optical techniques is applied to regular research of influence of radiating factors on structure and composition of a surface of metals and alloys. It is shown, that ellipsometry allows to investigate the development of defective structure on a surface of the irradiated metals and alloys at initial stages when other not destroying techniques yet do not allow possibility to do it. It is shown, that in the case of the radiating nature of damages of a blanket traditional models of processing of ellipsometric data based on homogeneous layers, can yield physically incorrect results. For the first time for modelling of a surface of metals and alloys after radiating processing by ions of deuterium on the basis of ellipsometric data models of non-uniform layers are used. It is shown, that only in this case it is possible to construct physically consistent picture of development of defective structure. Field of application: physics of a solid state, the physics of thin films, the radiation physics
