Tutorial Introduction to the XPS technique

CasaXPS 2.3.25 is now the release version. New features are documented in pdfs added to the web-page: www.casaxps.com/casaxps-traini...
An introduction to the XPS technique is presented within this video. The contents of the video are intended to prepare those new to XPS with an understanding for the physical reasons for the characteristic peak and background shapes seen in typical spectra.

Great intro!!

Thank you for the wonderful explanation. Would you please let me know what the difference is between binding energy and work function? I would greatly appreciate it if you could clarify the difference.

[@casaxpscasasoftware4605]

Binding energy is an energy that is required to move an atom from the initial state to the final state releasing a photoelectron with a given kinetic energy. However, there is a potential difference that the photoelectron then experiences between the sample and being detected, so the recorded kinetic energy for a photoelectron is lower than the true binding energy. The work function is typically the name given to the energy required to calibrate the energy of a reference photoemission peak, such as Ag 3d5/2 so that the reference peak, as recorded appears at the energy expected for that peak on a binding energy scale. If you would like more information about work functions then a place to start is aip.scitation.org/doi/full/10.1063/5.0086359.
