Modern research techniques with radioactive isotopes were used to study the transport characteristics, (conductivity and diffusion) in chalcogenide membrane materials of the Ag2S-As2S3-TlI system. It was demonstrated that, on raising the silver sulfi

Silver tracer diffusion study of homogeneous Ag 2 S-As 2 S 3 glasses has been realised over an extremely wide composition range covering nearly five orders of magnitude in the silver concentration from 4 × 10 4 % (4 ppm) to 33.3 at.% Ag. Three chara

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 spectroscopy (SNMS). It w

In contrast to the usual behaviour 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 mater

Homogeneity and electrical characteristics of Ag2S–As2S3 glasses with silver concentrations ranging between 0.012 and 9.8 at.% have been investigated. It was found that diluted vitreous alloys (x=0.012–1.2 at.% Ag) appear to be homogeneous accord

The short-range order in semiconducting x Cu 2 Se · (1 − x )As 2 Se 3 and mixed conducting x CuI · (1 − x )As 2 Se 3 glasses has been investigated using Extended X-ray Absorption Fine Structure (EXAFS) measurements at the Cu, As and Se K-edges.

Conductivity and silver diffusion measured using a 110m Ag tracer have been investigated in AgGeS and AgGeSbSe glasses with silver concentration ranging from 0.008 to 25 at.% Ag. It has been found that the room-temperature conductivity
