Ion transport and structure in chalcogenide glasses
TL;DR: In this article, the effect of the macroscopic structure in the electrical properties of chalcogenide glasses has been investigated and the results showed that the glasses from the limiting composition ranges are homogeneous while the glasses belonging to the central region are phase separated into two compounds with compositions close to GeS2 and Li2SiS3.

Universal trend of the Haven ratio in glasses: origin and structural evidences from neutron diffraction and small-angle neutron scattering
TL;DR: In this article, the Haven ratio in oxide and chalcogenide glassy systems exhibits a universal trend as a function of the mobile ion content x. The ion transport in extremely dilute glasses (x=30-100 ppm M+) is uncorrelated (HR≈1), but HR decreases rapidly with increasing x and remains nearly constant (HR=0.2-0.4) at x ⩾ 10 at.% Ag.

Glass formation and short-range order in chalcogenide materials: The (Ag2S)x(As2S3)1-x (0 <= x <= 1) pseudobinary tie line.

TL;DR: The onset of ionic conductivity as x is increased and the occurrence of two homogeneous glass-forming regions is therefore associated with a change in the coordination environment of the metal atom.

Structural study of GeS2−Ag2S glassy system by silver K-edge EXAFS experiments made at room and low temperature
TL;DR: In this article, the silver environments in (1−y)GeS 2 + yAg 2 S (0 2 S and Ag 8 GeS 6 ) phases were studied and the comparison between glassy and crystalline silver sites have allowed the silver surroundings in these glasses and to suggest a hypothesis of their structure.
