Figure 1. Ni 2p3/2 spectrum for sputter cleaned nickel metal [1].
Figure 2. Ni 2p spectra of NiO (A and B) and Ni(OH)2 (C and D) showing three different Shirley background configurations. (B) and (D) provide detail on the backgrounds at the low intensity region between the Ni 2p3/2 and Ni 2p1/2 portions of the spectra for NiO and Ni(OH)2, respectively. The fitted peaks use the Shirley background across the 2p3/2 portion of the spectra [2].
The work from [3] extends this approach to include fitting parameters for NiCr2O4 and NiFe2O4 (Figure 3), with fitting parameters also presented in Table 1. Ni 2p spectra of these two species are provided in Figure 2. Fitting parameters for the nickel halide (NiF2, NiCl2, NiBr2] series can be found in reference [4]. Also presented in [4] are Ni LMM Auger peak-shapes and Auger parameters for a variety of Ni species.
