XPS Spectra - casaxps

XPS is a quantitative technique in the sense that the number of electrons recorded for a given transition is proportional to the number of atoms at the surface.In practice,however,to produce accurate atomic concentrations from XPS spectra is not straight forward.The precision of the intensities measured using XPSXPS Spectra - casaxpsXPS is a quantitative technique in the sense that the number of electrons recorded for a given transition is proportional to the number of atoms at the surface.In practice,however,to produce accurate atomic concentrations from XPS spectra is not straight forward.The precision of the intensities measured using XPSXPS Interpretation of ZincInterpretation of XPS spectra. If zinc is buried (under carbon,for example),Zn Auger peak may be observed even if Zn2p is not (due to difference in electron kinetic energy).Similarly,Zn3p (very high kinetic energy) may be observed even if Zn2p is not.
