“…Our preceding research on ternary Se-Te-In composition signifies that In = 6 at. wt.% has greater thermal stability among investigated alloys [18,19]. Furthermore, in our earlier measurements on AC conductivity and dielectric study in Se-Te-Pb system illustrate considerable influence of Pb addition on conduction mechanism [17].…”

Pb additive nanochalcogenide materials are becoming well-known materials in modern optoelectronics. In this paper, multicomponent Se-Te-In-Pb nanochalcogenide alloys are prepared using melt-quenching technique. The physical and submicron structural features of investigated system are reported and discussed. Characteristic peaks in x-ray spectra signify nanorange of each sample under investigation validated by FESEM and HRTEM. Influence of Pb content on examined composition has been deliberated with respect to their physical characterization namely average coordination number (), mean bond energy (), crosslinking density (X), lone-pair electrons (L), fraction of floppy modes (f), constraints (N c ), electronegativity (χ), cohesive energy (CE), glass transition temperature (T g ), and heat of atomization (H s ). It is realized that addition of Pb content, enhanced N c , X, and . Whereas, , L, f, χ, CE, T g , and H s decrease with Pb addition. Cohesive energy is analyzed through chemical-bond approach. T g is estimated by Tichy-Ticha and Lankhorst approaches and are found in consistent with experimental results. The band gap of investigated system has been calculated theoretically by Shimakawa's relation and deduced results are analyzed through cohesive energy, electronegativity, and average single-bond energy. Also the compositional dependence of experimentally derived optical band gap has been analyzed and discussed.

The effect of some additives Cd, In and Sb on thermally-induced crystallization behavior of glassy Se 80 Te 20 alloy is studied by Differential Scanning Calorimeter (DSC). Kinetic parameters related to the crystallization of glassy Se 80 Te 20 and glassy Se 80 Te 10 M 10 (M = Cd, In, Sb) alloys have been analyzed using different non-isothermal methods. The activation energy of crystallization (E c ) is determined using non-isothermal DSC data. The rate of crystallization and avrami index (n) are evaluated for each glassy alloy. The effect of metallic additives Cd, In and Sb on different kinetic parameters of crystallization of glassy Se 80 Te 20 alloy is also discussed.
