  1. Electron Spectroscopy ESCA & AES

  2. Electron Spectroscopy • Fundamental Processes

  3. ESCA / XPS

  4. ESCA

  5. Information obtained from XPS • The peak position gives information about the element present. Referred to as a chemical shift • The binding energy increases as the oxidation state of the element increases. • The binding energy increases as the electronegativity of the attached atoms to the element of interest increases. • The intensity gives information about the element concentration. • The angle of collection provides depth profile information.
