XPS spectra are obtained by irradiating a solid surface with a beam of X-rays and measuring the kinetic energy of electrons that are emitted from the top 1-10 nm of the material. A photoelectron spectrum is recorded by counting ejected electrons over a range of kinetic energies. The energies...

Using a combination of ambient-pressure XPS and CeO/YSZ/Pt single-chamber cells, we carry outspectroscopy to probe oxidation states of all exposed surfaces in operational SOCs at 750°C in 1mbar reactant gases Hand HO. Kinetic energy shifts of core-level photoelectron spectra provide a direct ...
What is X-ray photoelectron spectroscopy (XPS)? XPS can measure the elemental composition, empirical formula, chemical state, and electronic state of the elements within a material. XPS spectra are obtained by irradiating a solid surface with a beam of X-rays while simultaneously measuring the kin...
