Bereznyak O. The effect of electron irradiation on the structural-phase state of aluminosilicates and gallium arsenide

Object: The structural-phase transformations under the influence of electron irradiation. The purpose: establishment of conformities to the law of high-energy electrons influence on a structure, phase composition and properties of aluminosilicates and gallium arsenide. Methods: infra-red spectroscopy, crystal optics analysis, x-ray structure analyses, differential thermal analysis. Results: It is established that dehydroxylation, disordering of crystal lattice and forming of mullite and cristobalite take place in pyrophyllite under electron irradiation. A 50 volume % areas of amorphyzations appearance is found in albite under irradiation. Alteration of crystalline grate is set exposed to the rays of orthoclase with forming of sanidine. It is discovered that over an irradiation the electrons of monocrystals of gallium arsenide results in the diminishing of width of the restricted power area due to the appearance of additional imperfect levels. In specimens with own conductivity the concentration of freetransmitters of charge as a result of their capture by radiation defects diminishes above an irradiation, and the de-serialized areas appear. The field of application: physics of solid state, radiation materials science, space microelectronics, ecology
