Notice: Technical Issues with Downloads

The site is having some technical issues with some downloadable materials.  We are working on a solution for this.

XPS Reference Pages

This site contains information gained from decades of X-ray photoelectron spectroscopy (XPS) analyses of an enormous variety of samples analyzed at Surface Science Western laboratories located at the University of Western Ontario. Originally this site was designed as a place for students and our clients to access valuable tips and information. It has since been opened to all those interested in the XPS technique. Summaries of literature data, relevant references and unpublished data taken of well characterized standard samples are presented. Also curve-fitting tips, instrument set-up tips (specifically for the Kratos AXIS Ultra and Kratos AXIS Nova), and CasaXPS tips pertaining to questions we normally get from our students and clients, and other odd bits of information are presented.
