X-ray Photo Emission (XPS)
Angle-resolved photoemission
X-Ray Electron Spectroscopy (XPS) or Electron Spectroscopy for Chemical Analysis (ESCA) is a surface sensitive method with a typical information depth of 1 - 5 nm corresponding to 4 - 20 atomic or molecular monolayers, determined by the mean free path of electrons. The imnaged and analyzed area varies between 2 - 500 um with a sensitivity limit of 0. 1- 1 % of a monolayer corresponding to 1012 - 1013
atoms/cm2 or 10-15 - 10-16 g within the analyzed volume.

Ultraviolet Photo Emission (UPS)
Angle-resolved photoemission
X-Ray Electron Spectroscopy (XPS) or Electron Spectroscopy for Chemical Analysis (ESCA) is a surface sensitive method with a typical information depth of 1 - 5 nm corresponding to 4 - 20 atomic or molecular monolayers, determined by the mean free path of electrons.
