“…Similar result obtained by A. K. Singh for Se-Zn-Te-In multi-component chalcogenide glasses [18]. A few works on heat capacities has been carried out on ternary chalcogenide glasses having different compositions [19][20][21][22].This kind of heat capacity change trend in all likelihood arises due happening of large number unsaturated bonds in complicated stoichiometry. Heat capacity at Tc defines the energy storage capacity of the materials for various physical applications.…”

Differential Scanning Calorimetry (DSC) is performed at different heating rates under non-isothermal conditions to study the heat capacities studies of glassy Se 75 Te 15-X Cd 10 In X (x=0, 5,10and 15) alloys.Heat capacities of Se 75 Te 15-X Cd 10 In X (x=0, 5,10and 15) chalcogenide glasses at glass transitions (T g ) and crystallisations temperatures (T c ) werementioned in this work. The evaluated endothermic (ΔC pg ) and exothermic (ΔC pc ) heat capacities of Se-Te-Cd-In system varies with alloying concentrations and maximum at threshold composition (5 at wt.% of In). This could be explained on the basis of chemical bond theory of the solids.

“…Essentially, ternary Se−Zn−Te glass forms the cross−link heteronuclear metastable state struc− ture. The existing heteronuclear bonds have produced the defects in the density of states owing to the occurrence of dangling bonds in alloys stoichiometry [136][137][138][139][140][141].…”

Amorphous semiconductors or chalcogenide glasses are the key materials in modern optoelectronics to make comfortable life of our society. Understanding of physical properties (like microstructure, thermal, optical, electrical) of these materials is important for their different uses. Predominant study of physical properties of the metal containing multicomponent chalcogenide glasses have attracted much attention, due to their interesting variable features and wide range of structural network modifications. Structural modifications in these materials are usually described with respect to the values of structural units (or average coordination number). In significance to this, the present work demonstrates the chronological development in the field of chalcogenide glasses along with scanning electron microscopy (SEM) morphologies. Optical, electrical and thermal correlative properties of recent developed Se93−xZn2Te5Inx (0 ≤ x ≤ 10) metallic multicomponent chalcogenide glasses are discussed. Variation in SEM morphology, refractive index (n), extinction coefficient (K), optical energy band gap (Eg), electrical conductivity (σav), crystallization activation energy (Ec) and glass forming ability (GFA) with structural units of Se-Zn-Te-In glasses have been demonstrated in this study. Subjected materials thermal, optical and electrical parameters have been achieved higher and lower in a respective manner at the threshold structural unit value 〈r〉.

Chalcogenide glasses or amorphous semiconductors are applicable materials in modern optoelectronics. Understanding of thermal, optical, electrical and structural properties in these materials is useful to demonstrate their potential uses. Particularly physical properties of metal containing chalcogenide glasses are getting much attention owing to their interesting features and wide range structural modification. This work presents a chronologic development in metal containing chalcogenide glasses and a correlation between optical, electrical, thermal parameters for recent developed Se-Zn-In alloys. Specifically, the variation of optical energy band gap (E g , electrical conductivity (av , crystallization activation energy (E c and Hruby number (GFA-glass forming ability parameter) with indium atomic percentage of Se 98−x Zn 2 In x (0 ≤ x ≤ 10) chalcogenide glasses is described. Subsequently, the variation of refractive index (n), E g , av , E c and Hruby number with average coordination number r of under examined systems is also discussed. Minimum and maximum variations in above physical parameters are obtained at threshold composition (6 at. wt% of In) and corresponding threshold structural unit r value.
