XPSPEAK is a specialized Windows-based application designed for the analysis of XPS spectra. Developed by Raymund Kwok, it allows users to perform background subtraction (Shirley, Tougaard, or Linear) and fit peaks using Gaussian-Lorentzian sum or product functions. Key Features:
Your goal is to minimize the Chi-square value, but don’t over-fit. If you need 10 peaks to fit one envelope, your model might be physically unrealistic.
In the same Properties menu, check "Run this program as an administrator" to ensure it has the permissions needed to save your work files. Why Use XPSPEAK Over Modern Software? xpspeak download
