Fe compounds can be reduced by Ar ion sputtering, even at relatively low ion. Case 2, the KE of the emitted electrons increases due to the repulsive forces between the charged surface and emitted electrons. Case 1, the emitted electrons have a reduced KE by a few tens of eV Identification remains possible.

A convolution of the shift distribution with the XPS lineshape (e.g. Carbon-based compounds are the basis for all living systems and comprise the structure of fossil fuels in the form of hydrocarbons. Fe oxide peaks are significantly shifted to higher binding energy than the metal. At intermediate neutralisation times ( 10 15 10 16 s) the XPS shift is distributed between 0 and E max. Carbon’s small size allows it to form multiple bonds with many other small atoms, including carbon atoms, and is prevalent in a large number of chemical compounds. Four allotropes of carbon are known: amorphous (e.g., charcoal and soot), graphite, diamond, and fullerenes. This video shows multiple peak fitting of RamanSpectroscopy.
