Photoelectron spectroscopy of ceria: Reduction, quantification and the myth of the vacancy peak in XPS analysis Surf. Interface Anal. (IF 1.7) Pub Date : 2023-09-04 David J. Morgan
Primarily due to its inherent redox chemistry, ceria (CeO2) is of use in many diverse areas of research. However, there is a wealth of misinterpretation of the oxygen spectra when discussing the result of damage or reduction to the CeO2 lattice, especially with regard to a signal in this region attributed to oxygen vacancies. In this paper, it is shown that this peak cannot be due to vacancies and

Surface analysis insight note. Principal component analysis (PCA) of an X-ray photoelectron spectroscopy image. The importance of preprocessing Surf. Interface Anal. (IF 1.7) Pub Date : 2023-07-31 Behnam Moeini, Tahereh G. Avval, Neal Gallagher, Matthew R. Linford
This Insight Note follows two previous Insight Notes on X-ray photoelectron spectroscopy (XPS) image analysis that dealt with the importance of analyzing the raw data and the use of summary statistics. As a next step in the exploratory data analysis (EDA) of XPS images, we now show principal component analysis (PCA) of an XPS image. PCA is appropriate when the spectra in a data set are correlated to
