Notes:
For the improvement of quantitative surface analysis using Auger electron spectroscopy (AES) we propose an Ni—Co alloy system as a candidate for a ‘primary reference material’ to be used for evaluating the accuracy of quantitative surface analysis. A Ni—Co alloy was chosen for two reasons. Firstly, the concentrations of the alloys (Ni49Co51,Ni75Co25) at the surface and in the near-surface region were found to be homogeneous, i.e. phenomena such as preferential sputtering and ion irradiation-induced surface segregation were no observed with angle-resolved XPS measurements during 1 keV Ar+ ion sputtering. Secondly, the corrections of matrix effects of Ni—Co alloys, such as the atomic density, the back-scattering factor and inelastic mean free path corrections, were calculated and found to be negligibly small.
