In the structural characterization of amorphous materials, the knowledge of the correlation distances and coordination numbers has a key importance. When several correlation distances overlap in the same diffractogram, obtaining the coordination numb

Ge 15 As 15 Se 70− x Te x materials with x = 56, 60 and 63, of potential use in IR-integrated optics, were prepared by the classical melt-quenching method. A macroscopic phase separation was observed with a crystalline phase on the top and an amorp

This work is focused on the fabrication of a chalcogenide rib ARROW structure. Three chalcogenide films of two different compositions (Ge33As12Se55 and Ge28Sb12Se60) were stacked on a silicon substrate, and the upper layer etched by a reactive physic

In order to study the ion dynamics of several inorganic glasses, we have taken conductivity spectra, extending from a few hertz up to the terahertz regime. At high frequencies the dynamic conductivity is governed by vibrational contributions, whereas

The relative arrangement of sodium and lithium ions in mixed alkali thiogermanate glasses of composition [(Na2S)1-y(Li2S)y]0.5(GeS2)0.5 (y = 0.20, 0.40, 0.50, 0.60, 0.80) has been studied by 23Na-{7Li} spin echo double resonance (SEDOR) spectroscopy.
