Figure 2: Constraint analysis of Ge–Se melts.
From: Revealing the role of molecular rigidity on the fragility evolution of glass-forming liquids
(a) Global MD constraint count of the liquid (1,050 K), compared with a count in the glassy state (300 K). The broken line represents the Phillips–Thorpe constraint count nc=2+5x (ref. 9). (b) Contourplots of the Ge BB constraint distribution among the structure for selected compositions. They have been generated by focusing on the constraint distribution inside a slab of 3.2±0.2 Å. (c) Calculated Ge BB (black) and BS (red, right axis) constraint density as a function of Ge content. (d) Variance σnc of the Ge BB constraint population.
