Percolation transition in Ag-doped germanium chalcogenide-based glasses: conductivity and silver diffusion results
TL;DR: In this paper, conductivity and silver diffusion measured using a 110m Ag tracer have been investigated in Ag-GeS and Ag-Sb-Se glasses with silver concentration ranging from 0.008 to 25 at.% Ag.
Journal ArticleDOI

M. Miloshova,E.A. Bychkov,V. Tsegelnik,V Strykanov,H. Klewe-Nebenius,Michael Bruns,W. Hoffmann,Philippe Papet,J. Sarradin,Annie Pradel,Michel Ribes +10 more
TL;DR: In this article, the sensitivity mechanism of mercury ion microsensors based on AgBr-Ag 2 S-As 2 S 3 thin films has been investigated using 110 Ag tracer exchange experiments, X-ray photoelectron spectroscopy (XPS) and secondary neutral mass spectrograph (SNMS).
Journal ArticleDOI
110Ag tracer diffusion study of percolation transition in Ag2S–As2S3 glasses
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.

Degenerated mixed cation effect in CuI–AgI–As2Se3 glasses: 64Cu and 110Ag tracer diffusion studies

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.
Journal ArticleDOI
64CU Tracer Diffusion in Copper Chalcogenide Glasses
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.
