Zinc analysis is typically performed on the Zn 2p photoemission, however obtaining the Zn KLL auger region is often paramount for interpreting the data correctly. There may be a slight overlap between the Zn 2p peaks and the O and V KLL augers from Al X-rays, however it should not impede deconvolution, partly due to the large doublet separation (23 eV).
Common binding energies for Zinc species may be found below:
|Species||Binding energy / eV||Charge Ref.||Ref.|
|Zn||1021.65||Au 4f / 83.95 eV||1|
|ZnO||1021.7||C 1s / 285 eV||2|
While the separation above may be small, as mentioned previously, the Zn LMM auger may assist in spectral understanding via the modified Auger parameters (table 2).
