F1s peak shapes are normally symmetrical. Fluorine tends to induce large chemical shifts in other elements, but within a given class of fluorine compounds (metal fluoride or organic fluorine), …

The process of peak-fitting high energy resolution XPS spectra is a mixture of scientific knowledge and experience. The process is affected by instrument design, instrument components, …

Sadly, while central to XPS, peak fitting of line-shapes to spectra is far from simple and if treated as a black-box tool will almost always yield incorrect results.

These reference pages contain tips and techniques that are designed to help both the novice and advanced XPS user.

Feb 1, 2024 · In summary, the intent of this article is to describe common errors that are observed in XPS data collection and peak fitting along with examples of good and bad XPS peak fitting …

We have presented four case studies of fitting bell-shaped curves to XPS data that illustrate the importance of both estimating the best possible peak shapes and using constraints in …

Peaks from the XPS spectra give relative number of electrons with a specific binding energy. The shorter the peak, the less electrons represented.

After “Data Processing and Charge Shifting” all chemical state spectra, then you must choose the Peak-fitting Parameters for your spectra. The words highlighted using Dark-Red Bold lettering …

The ultimate energy resolution of an XPS spectrometer is usually measured using the full width at half-maximum intensity (FWHM) of the Ag 3d5/2 peak from sputter cleaned silver.
