Abstract
A detailed analysis of X-ray diffraction data for GexSb40-xS60 glasses indicates the existence of a topological phase transition and medium- range order related not only to the first but also to the pre-first sh arp diffraction peak. The compositional dependence of the intensity, t he correlation length and the ratio between the position and the width of the two peaks are compared. Differences between the two peaks are revealed and their structural implications are discussed.
