Electronegativity difference, atomic size parameter and widths of supercooled liquid regions of Sb2S3–As2S3–Sb2Te3 glasses

In Situ Electron Beam Amorphization of Sb2Te3 within Single Walled Carbon Nanotubes

“…• C followed by rapid quenching, for example, in ice water [22], or (ii) electron beam irradiation above some minimum electron flux threshold [15]. Bundles of SWNTs filled initially with crystalline Sb 2 Te 3 were therefore subjected to low to moderate electron beam doses ranging from 0.8 pA cm −2 to 1.5 pA cm −2 in the timeresolved images reproduced in Fig.…”

Study of some numerical characteristic parameters of Sb2S3-As2S3-Sb2Te3 vitreous compositions calculated from their chemical formula obtained by EDS experiments

“…The chemical composition of various powder samples of Sb 2 S 3 -As 2 S 3 -Sb 2 Te 3 system corresponds to the average of three analyses. The results of EDS analyses for some binary and ternary samples of Sb 2 S 3 -As 2 S 3 -Sb 2 Te 3 system are presented in tables 1-5 [3]. The above tables indicate that there are slight discrepancies between the experimental and theoretical atomic percentages of the studied samples.…”

Estimations and implications of the mean binding energy and the fluctuation between the structural units in chalcogenide glasses

“…Hence, by using Eq. (8), N B is estimated to be N B = 3.4 / 0.56 ≈ 6.1. If we assume that E 0 is equal to ε 0 , it is possible to calculate the mean coordination number of the structural unit, Z 0 .…”

“…Another example is the finding of a good correlation between the glass transition temperature T g and the overall mean bond energy bE> for various kinds of chalcogenide glasses, which has been found by using the covalent bond approach proposed by Tichý and Tichá [6]. This approach has found a wide field of application in the study of chalcogenide glasses [7][8][9]. The theoretical methods mentioned above have provided insightful understanding on nanoscale phenomena that occur accompanied by the composition variation in chalcogenide glasses.…”
