| Popis: | International audience; Dependence of glass transition temperature Tg (K) on overall mean bonding energy E (kJ/mol) in arsenoselenide glass reexamined under per-atom calculations is shown to obey linearized master equation Tg ≅ 418⋅(E–1.13). Compositional variations in Tg against molar volume Vm are plotted for g-AsxSe100- x taken within (0 ≤ x ≤ 65) domain assuming preferential cohesive Van der Waals (VDW) bonding between network-constituting entities. The Tg values are found to vary as inverse-αth power of Vm, attaining distinct values for different networks, in part, 0D-molecular (α=6/3= 2), 1D-chained (α=5/3), 2D-layered (α=4/3), and 3D-spatial (α=3/3=1). These variations originated from macroscopic geometry of VDW interaction are linearized in log-log presentation for networks dominated with chain-like 1D-entities (0 ≤ x |
