Xps Of Cu 2p Spectrum In A Copper Ferrite And B In Cobalt Dopped As presented in fig. 3a, the deconvoluted high resolution cu 2p xps spectrum of cu 433 k is comprised of two peaks at 933.67 and 934.27 ev are assigned as cu 2p 3 2 and 954.23 ev corresponds to cu. Steps undertaken include the following: (i) an examination of existing cu 2p 3 2 main peak and cu 2p 3 2 – cu l 3 m 4,5 m 4,5 auger parameter literature data, (ii) analysis of a series of quality standard samples, (iii) curve fitting procedures for both the cu 2p 3 2 and the cu l 3 m 4,5 m 4,5 spectra (as well as associated anions), (iv.
Copper вђ Harwellxps Guru Table 2 shows similar results to those shown in table 1 from our work [4] for a series of standard samples. in this analysis, a statistical separation of the cu 2p 3 2 peak position for cu(0) and cu 2 o is achieved. this should be expected, as most spectrometer calibration procedures include referencing to the iso standard cu metal line at 932. The binding energy of the main cu 2p 3 2 and cu 2p 1 2 photoemission lines are in correspondence with the iso calibration standard reference values [27], [39] and other authors [8], [27]. download: download high res image (324kb) download: download full size image; fig. 1. peak fitting analysis of the metallic cu 2p photoemission spectra. The reason for using a model is so that it is clear which region corresponds to the peak and which corresponds to the background. the two metal peaks, 2p 1 2 and 2p 3 2, have a higher intensity in the pure material, a lower binding energy, and are sharp. however, because the metal is under the oxide layer, they have a small intensity even. Figure 3 c,d shows the high resolution xps spectra of s rgo cus, where the two peaks centered at 932.8 and 952.9 ev for the cu 2p 3 2 and 2p 1 2 . the cu 2p 3 2 was further deconvoluted into two.
