First-principles molecular dynamicsof glassy structures


C. Massobrio

Institut de Physique et Chimie des Matériaux de Strasbourg, 23 Rue du Loess, BP 43, F-67034 Strasbourg, France


The talk will be devoted to a description of methodological tools and results obtained therewith when employing first-principles molecular dynamics to model topological properties of glasses [1-6]. A strong focus will be given to the correlation between structural and electronic features that is inherent in the application of density functional theory related methods to the optimization and evolution with temperature of disordered systems. Most of our research efforts have highlighted chalcogenide systems and issues related to intermediate range order, chemical disorder, identification of structural motifs and establishment of robust predictive power for underlying theoretical scheme (appropriate use of exchange-correlation functionals). We employ the Wannier center analysis to assess changes in the iono-covalent properties of this materials (see Fig.1). Quite recently, we have extended our studies to the atomic-scale understanding of ternary phase-change materials, by providing a precise description of topologies not accessible to experimental measurements. We have also considered pressure effects as a way to inducing structural transformations.
