Data sets for the paper "Topological Ordering and Viscosity in the Glass-Forming Ge-Se System: The Search for a Structural or Dynamical Signature of the Intermediate Phase"

Abstract

Data sets used to prepare Figures 1 – 14 in the article entitled “Topological Ordering and Viscosity in the Glass-Forming Ge-Se System: The Search for a Structural or Dynamical Signature of the Intermediate Phase,” published in Frontiers in Materials: Glass Science. The files are labelled according to the figure numbers. The data sets were created using the methodology described in the manuscript. Each of the plots was created using Origin software (http://www.originlab.com/). The data set corresponding to a plotted curve within an Origin file can be identified by clicking on that curve. The units for each axis are given on the plots. The data sets obtained by other authors are identified in the figure captions. The data sets correspond to measurements made on glassy samples in the GexSe(1-x) binary system for x in the range from 0 to 0.4. Figures 1 – 5 give the composition dependence of the liquidus temperature, mass density, molar volume, glass transition temperature, and non-reversing heat flow, respectively. Figures 6 – 10 give the composition dependence of the measured neutron diffraction results for the glasses and related parameters. Figure 11 shows fits of the MYEGA model to the measured viscosity data for several Ge-Se liquids. Figure 12 – 14 give the composition dependence of the fragility index, ratio of the glass transition temperature to the liquidus temperature, and viscosity at the liquidus temperature, respectively.
