“…This result is consistent with the decrease in the vitreous transition temperature. Similar results were observed when replacing arsenic by tellurium in the As-Te-Sb bulk glass system [23]: an increase in the atomic percentage in Te (with constant at.% Sb) is responsible for a decrease in T g and a decrease in the microhardness. In order to compare the microhardness values of the co-thermally evaporated films with that of a bulk glass of the same binary system, the Vickers microhardness of a Te 77.5 Ge 22.5 glass elaborated by twin roller quenching was measured [8].…”

“…Compared with oxide glasses, the mechanical strength and thermal stability of chalcogenide glasses are significantly lower, whereas their thermal expansion coefficients and the temperature coefficients of their refractive indices are higher. Because of the higher atomic masses and lower bonding-force constants in the chalcogenide compositions, the range of IR transparency is essentially broadened towards higher wavelengths [153][154][155][156][157][158][159][160][161]. Goryunova and Kolomiets [162,163] were among the pioneers in revealing the rules governing the GFAs of chalcogenide glasses, namely, the size of the glass-forming region in a two-or three-component chalcogenide alloy decreases when one of the components of the 4th (Ge, Sn), 5th (As, Sb, Bi), or 6th (S, Se, Te) main subgroups of the periodic table is replaced by an element with a greater atomic number [164,165].…”

In constant use since ancient times, glass remains a highly valued material that is ubiquitous in daily life. Today, glass has become an indispensable and essential component in such fields as photonics, optical communications, photovoltaic cells, household appliances, vehicles, and building materials. However, one of major stumbling blocks for its optimal use is the low glass-forming ability (GFA) of many glass-forming compositions, which is far from being adequately solved. Understanding the nature of the GFAs of materials is the key to the development of new glasses with improved properties and manufacturability for various engineering applications. The rapid development of new glasses over the past several decades has led to increasingly complex material compositions. However, the phase diagrams of these materials have yet to be properly addressed even though such diagrams are extremely useful in rationally designing glass-forming compositions and predicting their behavior in pursuit of new functional glasses with particular desired properties. In this context, the present review strives to provide new insights into the formation of glasses and glass-forming regions through quantitative calculations and predictions based on a comprehensive survey and analysis of the existing experimental observations and theoretical considerations, a considerable portion of which stems from work performed in our own laboratory.

“…The photostructural changes which have influenced changes in the optical and electrical properties of the chalcogenide layers are related with the amorphous to crystalline phase transformation. These processes are actually used for the purposes of recording and deleting information in the chalcogenide layer [6]. Crystallization kinetics is an important part of the amorphous study.…”
