Fig. 5

a Translational order in SiO2 glass as a function of the parameter z obtained in our experiment with MD-RMC modeling (Exp+MD-RMC) and MD simulations with BKS and MSD models at 0 and 5.2 GPa. Source data are provided as a Source Data file. b Partial pair distribution functions of Si-Si [gSiSi(r)]. The gSiSi(r) of the BKS and MSD models are displayed by a vertical offset of +2 and +4, respectively. c–e Structural features of SiO2 glass with the characteristic distribution of z = 1.7 Å in the BKS model at 5.2 GPa (c), z = 2.4 Å in the BKS model at 0 GPa (d), and z = 2.7 Å in the MSD model at 0 GPa (e). Blue and light blue spheres represent silicon atoms and red spheres represent oxygen atoms. Numbers represent distances to the nearest five silicon atoms (blue spheres) from a silicon atom shown by light blue.
