TL;DR: In this paper, a tracer diffusion study of homogeneous Ag 2 S-As 2 S 3 glasses has been carried out and three characteristic composition domains with drastically different ion transport properties have been found.

TL;DR: In this paper, the authors performed tracer measurements of ionic diffusion for several copper-rich glass compositions in the CuIAs2Se3, CuI-PbI2-I3-SbI3I3, As 2Se3 and As 3Se3 systems.

TL;DR: In contrast to the usual behavior of mixed cation glasses (large deviations from additivity with a pronounced minimum at the conductivity isotherms and a diffusivity crossover when guest cations reduce the mobility of ions coming from the host material), the CuI-AgI-As 2 Se 3 glassy system exhibits remarkable differences in the transport properties as mentioned in this paper.

TL;DR: In this paper, the diffusion coefficients in the CuI•As2Se3 system appear to be by three orders of magnitllde higher compared to those in the CU2Se•As•Se3 glasses.

TL;DR: In this paper, the I-Mossbauer spectroscopy was used to study the local iodine environment in the superionic x AgI·(1− x )As 2 Se 3 and mixed conducting (Cu +, hole) x CuI· (1− X )As 1 Se 3 glassy systems ( x =005-050) Well-resolved quadrupole-split multiplets, also characterised by a Gaussian-like distribution of the nuclear quadrupoles interaction constant ν Q, as well as distinctly different values of the isomer shift S
