Electron irradiation effects on phase stability of the E (Al18Cr2Mg3) phase have been investigated by high- angle annular dark-field scanning transmission electron microscopy and high-resolution transmission electro...
In a previous study, structure of silica gels prepared in a high magnetic field was investigated. While a direct application of such anisotropic silica gels is for an optical anisotropic medium possessing chemical res...
We report a comparative experimental study of the attenuation spectra transformations for a series of Yb doped alumino-germano silicate fibers with different contents of Yb3+ dopants, which arise as the result of irra...

The oxygen-related defects in CZ silicon during electron irradiation(1.5 MeV)and subsequent annealing in the range of 150-600℃were investigated by means of FTIR.In the electron irradiation CZ-Si,vacancy-oxygen comple...
Raman scattering measurements on Se-doped GaAs epitaxial layers and semi-insulating (SI) GaAs irradi-ated by 10 Mev electrons have been investigated. Several defect-related features were observed. We suggestthat the 2...
