EXAFS Spectroscopy Laboratory (EXAFS Lab) focuses on the study of materials structure using modern experimental and theoretical The analysis of EXAFS data measured on a material with a disordered local configuration environment around the absorbing atom can be challenging due to the proliferation of photoelectron scattering paths that must be considered in the analysis.

Advanced Functional Materials: A Perspective from Theory

X-Ray Absorption Spectroscopy: EXAFS and XANES - A Versatile Tool to Study the Atomic and Electronic Structure of Materials E. E. Alp, S. M. Mini, and M. Ramanathan X-ray absorption spectroscopy (XAS) had been an essential tool to gather spectroscopic information about atomic energy level structure in the early decades of this century. While single-scattering paths generally dominate most EXAFS spectra, multiple scattering paths can give important contributions, especially in well-ordered crystalline materials. A review is given of the results obtained in the field of materials science using the comparatively new technique of Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy. Particular emphasis is placed on the determination of the atomic distribution functions in amorphous and multi-component materials, especially metallic and oxide glasses, catalysts and alloys. EXAFS can be used as a method of surface analysis (SEXAFS) and is based on the measure of the variation of the X-ray absorption coefficient of a material sample.

When the X-ray photon energy (E) is tuned to the binding energy of some core level of an atom in the material, an abrupt increase in the absorption coefficient,  for noncrystalline and highly disordered materials, including solutions. the absorbing atom, while the EXAFS is used to determine the distances, coordination.

Polyhedral approach . Edge and corner sharing Edge sharing. Relative ratio of edge/face-corner sharing Over time, EXAFS has become more applicable to quantitative analysis of noncrystalline materials. When analyzing a single atom within a material, properties analyzed include coordination number, disorder of neighboring atoms, and distance of neighboring atoms. Of these three properties, radial distance is the only property reliably measured.

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.
