Chalcogenide glasses are defined as a new category of non-crystalline solids on the basis
of their characteristic covalent bonds and unique properties, such as broad infrared …

The microscopic origin of glass formation has been debated for over 50 years. It is generally
believed that glass formation is a kinetic phenomenon [1], although the aspects of liquid …

This book gives a pedagogical introduction to the physics of amorphous solids and related
disordered condensed matter systems. Important concepts from statistical mechanics such …

We present a topological model for the composition dependence of glass transition
temperature and fragility. Whereas previous topological models are derived for zero …

Chalcogenide glasses have the advantages of a wide transparency window (over 20 μm)
and high optical nonlinearity (up to a thousand times greater than that of silica glasses) …

Glass transition temperature and fragility are two important properties derived from the
temperature dependence of the shear viscosity of glass-forming melts. While direct …

Recent progress in the description of glassy relaxation and aging are reviewed for the wide
class of network-forming materials such as GeO 2, Ge x Se 1− x, silicates (SiO 2–Na 2 O) or …

Perovskite solar cells technology is one of the most advanced and fascinating technologies
in the field of photovoltaics due to its low-cost processing and delivering efficient power …

Glasses are widely used as analogues for the study of silicate melts. Although they are solid
materials, their structure is inherently complex and difficult to study. However, progress has …

Non-reversing relaxation enthalpies (ΔH nr) at glass transitions T g (x) in the P x Ge x Se 1−
2x ternary display wide, sharp and deep global minima () in the 0.09< x< 0.145 range, within …
