XPS is a surface sensitive and non destructive technique used for analysis of the elemental composition of a sample. The basic principle is shown below (the image is taken from Wikipedia).
XPS is a surface sensitive and non destructive technique used for analysis of the elemental composition of a sample. It relies on the photoelectric effect; X-ray photons irradiated onto a sample will cause electrons bound in the sample atoms to become free electrons inside the the sample as
