X-ray Photoelectron Spectroscopy (XPS) Peak Fitting of [Material Name] Using XPS Peak Fit 4.1

If you are searching for a "new download" because you cannot find the original file, proceed with caution.

Recommendation: Because of the security risks associated with downloading old executables from unknown "file hosting" sites, most surface analysis labs now recommend moving to open-source or actively maintained alternatives (see Section 4).

If you're having trouble finding XPS Peak Fit 4.1 or if there are issues with the download, consider reaching out to academic or professional forums related to surface analysis or materials science for recommendations on XPS analysis software.

XPSPeak 4.1 is a free, lightweight software program designed for the analysis and deconvolution of X-ray Photoelectron Spectroscopy (XPS) data

. Originally developed by Raymund Kwok, it is widely used in academic research to fit overlapping peaks and quantify chemical states. University of Warwick Core Features of XPSPeak 4.1 Peak Modeling

: Supports up to 41 component peaks with flexible shapes including Gaussian, Lorentzian, and mixed Voigt functions. Background Correction : Offers standard background subtraction methods such as , Tougaard, and Linear models. Parameter Constraints

: Users can lock or link parameters like peak position, Full Width at Half Maximum (FWHM), and peak area to ensure physical consistency. Advanced Tools : Features include the ability to combine 2 p sub 3 / 2 end-sub 2 p sub 1 / 2 end-sub peaks and fit multiple spectral regions simultaneously. ResearchGate Download and Installation

Extract all files to a new, dedicated folder on your computer. XPSPEAK41.exe

The application typically runs as a "portable" app, creating a sandbox folder for its settings. Washington State University Basic Analysis Workflow

XPSPeak 4.1 is a highly regarded, lightweight freeware tool for X-ray Photoelectron Spectroscopy (XPS) analysis, favored for its balance of simplicity and essential functionality. Key Features and Strengths

Essential Analysis Tools: It provides critical capabilities for routine XPS analysis, including Shirley background subtraction, Gaussian-Lorentzian peak modeling, and least-squares fitting.

Highly Flexible Constraints: One of its strongest selling points is the ability to lock or link parameters—such as peak position, FWHM (Full Width at Half Maximum), and area—giving researchers granular control over the deconvolution process.

User-Friendly Interface: The software uses a dual-window system: the top window manages active scans and background adjustments, while the lower window handles peak processing.

Portability & Compatibility: As a lightweight Windows application, it can be run as a "portable" app that stores settings in a sandbox folder, making it easy to use across different lab workstations. Critical Considerations

XPSPeak 4.1 is a widely used, free Windows application designed for visualizing and fitting X-ray photoelectron spectroscopy (XPS) data. Originally developed by Dr. Raymund Kwok, it is favored for its lightweight nature and specialized features like Shirley background calculations and Lorentzian-Gaussian peak fitting. Download and Installation XPS Peak Fit 4

The software is primarily hosted on academic archives and specialized software platforms:

Direct Download (WSU Archive): You can download the software directly from the Washington State University Archive, which provides a PDF guide with installation instructions.

Alternative Repositories: It is also available via Software Informer and GetWinPCSoft.

Installation Note: The software typically comes as a cabinet (.cab) file. You must extract the files into a new folder and run the XPSPEAK41 executable. For it to function properly, ensure all extracted files remain in the same directory. User Resources and Manuals

Official Manual: A comprehensive user guide for Version 4.1, covering peak constraints, background types (Shirley, Tougaard, Linear), and optimization, is available through the University of Warwick.

Video Tutorials: Step-by-step installation and analysis guides can be found on YouTube, such as this XPSPeak 4.1 Tutorial.

Research Applications: For practical examples of using the software in research (e.g., analyzing nitrogen in sewage sludge), you can refer to articles on ResearchGate. Key Features for XPS Analysis

XPSPeak 4.1 is a widely used, free Windows-based application for visualizing and fitting X-ray photoelectron spectroscopy (XPS) data. While the original university-hosted download pages (like at CUHK) may no longer be active, the software and its documentation are still accessible through several reliable institutional and researcher-maintained mirrors. Downloads and Manuals

Software Mirror: A downloadable version of XPSPeak 4.1 is available through the Scudiero group documents hosted by the Washington State University archive. Let’s walk through a typical workflow using the

Documentation (The "Long Paper"): The comprehensive manual for version 4.1, which details everything from installation to background constraints (Shirley, Tougaard) and peak optimization, can be found at the University of Warwick XPS links.

Additional Resources: Researcher Jens Uhlig's personal webpage also provides mirrors for both the software and the manual. Core Functionality

XPSPeak 4.1 allows for detailed control over various parameters to ensure physically meaningful fits:

Background Types: Supports Shirley, Linear, and Tougaard backgrounds.

Peak Parameters: Users can define peak types (p, d, f), adjust Gaussian-Lorentzian ratios, and apply peak constraints.

Constraint Management: It allows for constraining parameters like peak area, position, and width. Contemporary Alternatives
