Figure 3: Comparison between estimated and measured viscosities.
From: Revealing the role of molecular rigidity on the fragility evolution of glass-forming liquids
Comparison between the Stokes–Einstein calculated (filled symbols) viscosities at various Ge–Se compositions and experimental measurements of viscosity (open symbols) from Stølen et al.22 Senapati et al.23 and Guegen et al.24 Note that only Stølen et al. have investigated the high temperature region where numerical data can be directly compared. The solid lines correspond to fits using the Mauro–Yue–Ellison–Gupta–Allen (MYEGA) equation25 that describes with an increased accuracy the high temperature viscosities as compared with alternative fitting functionals26 (for example, Vogel–Fulcher–Tamman, VFT).
