What Does PEXAFS Stand For?

PEXAFS stands for Photoemission Extended X Ray Absorption Fine Structure

PEXAFS, or Photoemission Extended X Ray Absorption Fine Structure, is a spectroscopic technique that combines photoemission and X-ray absorption measurements to investigate the electronic and atomic structure of materials. It provides detailed information about the local environment of specific elements within a sample, allowing for the analysis of molecular and solid-state systems at the atomic level. This method is particularly valuable in studying complex materials, including catalysts, semiconductors, and nanostructures, by revealing the interactions between electronic states and the local coordination of atoms.
