Common Binding Energies – Be 1s #

Theory and Background #

Beryllium has a very low sensitivity in XPS, owing to very unfavourable photoionisation cross-sections (in fact, only Lithium has a lower cross-section).

As such it will be challenging to detect in low contents.

Experimental Advice #

Given the relatively low separation between multiple states, and the low intensity of the peaks owing to the unfavourable cross-sections, it can be advantageous to record the Be KLL auger also, since the Wagner plot of Be compounds may offer additional assistance in speciation.

See the work of Mallinson, Castle and Watts for more information.

Data Analysis Guidance #

Beryllium metal exhibits little asymmetry, and can be fit with a standard Voigt lineshape
