为了探索几种半导体玻璃和金属玻璃的局域和中程原子结构，利用改进的第三代同步辐射探测系统进行了反常X射线散射（AXS）实验，并利用反向蒙特卡罗（RMC）模型对所得数据进行了分析，获得了这些玻璃的部分结构因子，构建了它们的三维原子构型。以GeSe2半导体玻璃和Pd40Ni40P20金属玻璃为例，说明了AXS和RMC技术结合的可行性。对于含有轻元素的合金，还描述了与中子散射的附加组合的重要性。
In order to explore local- and intermediate-range atomic structures of several semiconducting and metallic glasses, anomalous X-ray scattering (AXS) experiments were performed using an improved detecting system suitable for third-generation synchrotron radiation facilities, and the obtained data were analyzed using reverse Monte Carlo (RMC) modelling to obtain partial structure factors and to construct three-dimensional atomic configurations of these glasses. Examples of GeSe2semiconducting and Pd40Ni40P20metallic glasses are demonstrated to exhibit the feasibility of the combination of AXS and RMC techniques. Importance of an additional combination with neutron scattering is also described for alloys containing light elements.
