Ivanitsky V. Formation of stochastic heterogeneous structure of amorphous chalcogenides AIV-BV-XVI systems

Research object. Thin amorphous films with thickness from 10 nm to 1000 nm and glass cuts with thickness 100 - 200 nм of two- and three components chalcogenide systems. Aim. The decision of a scientific problem on an establishment of laws and mechanisms of formation stochastic structure inhomogenitis of a different scale level in amorphous chalcogenide systems AIV-VV-HVI. Methods. RF-sputtering; thermal and laser evaporation; ultramicrotoming of glasses; scan and transmission electron microscopy; electron diffraction; wave-guide optics. Results, novelty. The dissertation is devoted to research of the general laws of display stochastic heterogeneous structures of amorphous films and glasses different chalcogenide systems at all scale levels: the short order, the intermediate order, mezoscopic, nanostructure and microstructures. Methods of electronic microscopy, electron diffraction and computer modeling are proved a dominating role at formation of structure amorphous chalcogenide films molecular complexes and multinuclear particles of a steam stream. On the basis of the comparative analysis it is shown precise correlation in behaviour reversive birefringence in amorphous films As-S(Se) and azobenzene polymers. It is underlined a generality of a structural basis of occurrence of effects induced birefringence in the given both types of materials. Field of implementation. Solid State Physics.
