An iterative method that adjusts the background shape based on the total area of the peak above it, ideal for metallic systems.
A robust commercial alternative tailored for advanced spectral decomposition.
XPSPEAK41 is a widely used, legacy Windows software program designed for peak fitting and analysis of X-ray Photoelectron Spectroscopy (XPS) data. Although it is an older tool, many researchers and students still seek it out because it is lightweight, completely free, and features a straightforward interface for processing spectral data.
: The ability to fit different XPS regions simultaneously, which significantly reduces optimization time for complex analyses involving multiple elements or spin‑orbit split doublets.
Features adjustable Gaussian-Lorentzian mixing ratios to accurately model asymmetric or symmetric peak shapes.
If you encounter missing .dll or runtime errors upon launching, you may need to install the Microsoft Visual C++ Redistributable packages or run the application using the "Troubleshoot compatibility" wizard built into Windows. Step-by-Step Data Fitting Workflow
A residual line showing large peaks or valleys indicates a missing chemical component or an incorrectly selected background type. Consider adding another peak or tweaking the G-L mixing ratio.
: Combines the thermal broadening (Gaussian) and lifetime broadening (Lorentzian) shapes.
results were a chaotic mountain of overlapping curves that refused to resolve into clear chemical states.
