The XPS database is in three parts.

  1. An introduction
  2. Curve-fitted data and binding energy tables
  3. Spectral data files containing the raw data used to generate the curve-fits

Also included on the CD is a demonstration version of CasaXPS. Even if you already have an XPS data processing package we would urge you to try out this software. The demonstration version alone provides a number of very powerful data processing features.

Introduction

A document detailing the procedure followed by Beamson and Briggs from sample preparation, through experimental procedure to the interpretation of the curve-fits.

The various sections are;

  1. Background
  2. Sample preparation, data acquisition conditions and binding energy referencing
    • Sample preparation and mounting
    • Data Acquisition
    • Correction of Binding Energy Scale for Sample Charging
  3. Surface Stoichiometry and Impurities
  4. Aspects of Spectrum Interpretation
    • Curve Fitting
    • Spectral features
  5. X-ray induced sample degradation
  6. Database Organisation
  7. References

Curve-fitted data

Data acquired on the Scienta ES300 spectrometer was curve-fitted and the results are presented here in both graphical and tabulated form.

The files are in Adobe’s Portable Document Format (pdf) and are accessible on many platforms using Acrobat Reader – a program freely available from the Adobe website. Versions of Acrobat Reader for Windows, Macintosh, Linux, Solaris and OS2 are supplied on the CD.

Raw spectral data files

All the spectral data acquired from the 111 polymers is available on the CD.

The spectra are presented in a number of different file formats to enable the data to be imported into the data processing software of all major instrument manufacturers and standalone packages.

File formats available on the CD include VAMAS (ISO 14976) standard data transfer format, Physical Electronics’ MultiPak and also ASCII energy-intensity paired files, each in various combinations of kinetic and binding energy and formatted for both UNIX and MS-DOS platforms. Both single-region and multiple-region VAMAS files are included. In total 17 different formats and naming conventions have been included.
