Novel theoretical 'filtering' to manage spectral peaks and chemical signatures
Core-level spectroscopies are called so because they obtain element-specific information of the electronic structure based on the ejection of a core electron. X-ray photoelectron spectroscopy (XPS) is one of those techniques, and it is one of the most important tools for surface analysis. XPS measures the kinetic energies of photo-emitted electrons, but currently the spectral peaks produced can be difficult to interpret. Given its utility and widespread use, the EU-funded THEOCORPES project is enhancing the performance of XPS with the help of theoretical modelling to more accurately identify the chemical environment tested. The complementary modelling will help XPS users enhance the interpretation of their experimental results in numerous fields.
