(a) The total structure factors S(Q) for PbSiO3 glass and liquid at 2.5 GPa and 300 to 1100 K (solid black curves). The dashed red curves are ambient-P measurements of PbSiO3 glass made at beamline ID11 at the ESRF. The inset shows comparison between the 300 K measurement at 2.5 GPa and the ambient-P glass in the low-Q region. (b) The total PDFs G(r) obtained from the corresponding S(Q) functions in (a) by Fourier transformation. For clarity, the results are displaced vertically. |
