The XPS (X-Ray Photoelectron Spectroscopy) it is also known as ESCA (Electron Spectroscopy for Chemical Analysis). This technique is based on the theory of the photoelectric effect that was developed by Einstein, yet it was Dr. Siegbahn and his research group who developed the XPS technique.

The electrons ejected ...
