Movie S2 2020-05-12 · Single atom catalysts (SACs) have recently attracted much attention. To identify the single atom materials, a combination of high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) and synchrotron radiation-based extended x-ray absorption fine structure (EXAFS) is typically used.

The x-ray absorption coefficient is usually normalized to unit step height. INTRODUCTION EXAFS in now widely used to probe the atomic scale structure of amorphous materials. Capabilities and limitations of EXAFS spectroscopy, in comparison with X-ray diffraction, are briefly reviewed. Its contributions to the field of amorphous materials are exemplified by recent results in the study of hydrogenated a-Ge and a-Si and amorphous to crystalline transition. 2.2. EXAFS from the nearest shells. The use of classical MD is limited by the simplicity of existing force-field models and is not applicable in situations where the electronic structure of a material leads to a strong local structure distortion such as, for example, in the case of the Jahn–Teller effect (Kunz & Brown, 1995).

EXAFS spectra are displayed as plots of the absorption coefficient of a given material versus energy, typically in a 500 – 1000 eV range beginning before an absorption edge of an element in the sample. The x-ray absorption coefficient is usually normalized to unit step height.

Abstract. The structure of amorphous alloys is an important field in materials research. The lack of an extensive regular structure in these amorphous materials, however, often limits the amount of unambiguous structural information which can be gained from conventional structural techniques such as x-ray, neutron, or electron diffractions. notably also for amorphous materials, liquids and molecular gases, where traditional diffraction techniques cannot be used. For materials without long range order, EXAFS is often the only practical way to study the arrangement of atoms. In the example in Figs.
