Systematic and collaborative approach to problem solving using X-ray photoelectron spectroscopy
Overview
Paper Summary
This paper proposes a systematic approach to XPS data analysis, emphasizing the importance of collaboration and prior knowledge. Using a molybdenum sulfate sample as a case study, the authors demonstrate a methodology for constructing peak models and interpreting complex spectra, highlighting the challenges posed by factors like surface contamination and overlapping signals. The analysis showcases how combining information from various sources can lead to a more accurate and comprehensive understanding of sample composition and chemical states, especially in cases of non-homogeneous samples, such as those of tribological origin.
