SUMMARY

In X-ray photoelectron spectroscopy (XPS) measurements, the full width at half maximum (FWHM) value may not remain constant across different oxidation states of the same element. This variability in FWHM is crucial for accurate fitting of the spectra. The discussion emphasizes the importance of considering oxidation states when analyzing amorphous transition metal oxide thin films, particularly in applications involving glass substrates.

PREREQUISITES
  • X-ray photoelectron spectroscopy (XPS) fundamentals
  • Understanding of full width at half maximum (FWHM) in spectral analysis
  • Knowledge of oxidation states in transition metals
  • Experience with fitting techniques in spectroscopy
NEXT STEPS
  • Research the impact of oxidation states on XPS peak characteristics
  • Learn advanced fitting techniques for XPS data analysis
  • Explore the properties of amorphous transition metal oxides
  • Investigate the effects of substrate materials on XPS measurements
USEFUL FOR

Researchers and analysts in materials science, particularly those focused on X-ray photoelectron spectroscopy, transition metal oxides, and thin film characterization.

Dear All,

for different oxidation states of the same element in X-ray photoelectron spectroscopy measurements, should the full width half maximum (FWHM) value be the same for all? Is this a parameter to fix in this case for the fitting?

I am studying an amorphous transition metal oxide thin film on glass.

Thanks a lot!
