Figure 2
EDCs at photon energies of 473, 481, 489, 497 and 505 eV, indicated as blue, green, yellow, red and light-blue lines, respectively. The gray area indicates the N KLL Auger peak. The red and blue areas indicate the energy windows, and their integrated intensities were used to derive the EXAFS spectra. The five photoelectron peaks are attributed to Si 2p and moved to higher kinetic electron energies as the photon energy increased. |
