Quantitative X-ray photoelectron spectroscopy of CuAu, CoNi and CuNi alloys using theoretical photoionisation cross sections or reference spectra
This paper studies the extent to which the accuracy of quantitative analysis of X-ray photoelectron spectroscopy is affected by neglect of the shake-up electrons. Three sets of alloys (CuAu, CoNi and CuNi) were studied. It was found that the accuracy of quantification from first principles based on the intensity in a narrow energy range around the peak energy can lead to errors of up to 114 %. The error is discussed in terms of the importance of shake-up effects. When reference spectra are applied, these effects are reduced and the Shirley method for background estimation then yields compositions for the considered alloys that differ by between 2 % and 22 % from those determined with an algorithm that is based on a physical description of the inelastically scattered electrons.
