Abstract

In this article, we review our recent structural studies on chalcogenide glass systems, Gex Se1-x and Asx Se1-x , using anomalous X-ray scattering (AXS) in combination with reverse Monte Carlo (RMC) modeling. We show to what extent the present AXS + RMC works are effective to solve the long lasting topics in these chalcogenide glasses, such as the validity of the 8-N bonding rule, the relation to the rigidity percolation theory, the validity of chemical order, and the origin of prepeak.
