## Description

- description: To investigate the relationship between the partial structures and
    the stiffness transition in AsxSe1−x glasses, anomalous X-ray scattering (AXS)
    and X-ray and neutron diffraction (XRD and ND) experiments were carried out. For
    the AXS experiments, anomalous terms near the absorption edges were experimentally
    obtained instead of the theoretical values with large ambiguities. The results
    were analyzed by reverse Monte Carlo (RMC) modeling to obtain partial structure
    factors, S i j(Q), partial pair distribution functions, gi j(r), and three-dimensional
    atomic configurations. The S i j(Q) and gi j(r) functions gradually vary with
    x; however, an important change was observed in the intermediate-range element-selective
    atomic structures (the so-called hyper-ordered structures) near the stiffness
    transition composition. With decreasing x across the so-called intermediate phase
    compositions, a rapid decrease of the As-As wrong bonds is visualized. However,
    the other anomalies found in Ge–Se glasses are not clearly observed, such as a
    rapid decrease in pre-shoulder position in SSeSe(Q), a rapid decrease in the number
    of edge-sharing connections, and an exclusion tendency of the connections between
    the As(Ge) atoms sharing two Se atoms, which may be related to the anisotropic
    pyramidal atomic configurations around the As atoms in the As-Se glasses in contrast
    to the isotropic tetrahedral ones around the Ge atoms in the Ge-Se glasses.
