Resonant Raman spectra of stoichiometric glass (g) g-As₄₀Se₆₀ have been investigated. It was observed that the increasing of excitation radiation energy hv>E₀ (E₀ is pseudogap width) changes a shape, intensity, and position ...

Chalcogenide vitreous semiconductors (ChVS) are used as memory elements, elements of fiber, integral and power optics [1–6]. The change of the synthesis conditions results in the change of structure and, as a consequence, ...
