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, Sij(Q), partial pair distribution functions, gij(r), and three-dimensional atomic configurations. The Sij(Q) and gij(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.
为了研究 AsxSe1-x 玻璃中部分结构与硬度转变之间的关系，我们进行了反常 X 射线散射（AXS）以及 X 射线和中子衍射（XRD 和 ND）实验。在反常 X 射线散射（AXS）实验中，通过实验获得了吸收边缘附近的反常项，而不是误差较大的理论值。通过反向蒙特卡罗（RMC）建模分析结果，得到了部分结构因子 Sij(Q)、部分配对分布函数 gij(r) 和三维原子构型。Sij(Q)和 gij(r) 函数随 x 逐渐变化；然而，在刚度转变成分附近的中程元素选择性原子结构（即所谓的超有序结构）中观察到了重要变化。在所谓的中间相成分中，随着 x 值的减小，As-As 错键迅速减少。然而，在 Ge-Se 玻璃中发现的其他异常现象并没有被清楚地观察到，例如 SSeSe(Q) 中前肩位置的快速下降、边缘共享连接数量的快速下降以及共享两个 Se 原子的 As(Ge) 原子之间连接的排斥趋势，这可能与 As-Se 玻璃中 As 原子周围的各向异性金字塔原子构型有关，而 Ge-Se 玻璃中 Ge 原子周围的各向同性四面体原子构型则与之相反。
