Generally, in the survey X-ray photoelectron spectra, we observe the background of the spectra is more at higher binding energy values as compared to that of the lower values. I wanted to know, why it is so? can anyone answer me?
Up to a limit, which is not sharply defined [1], the higher the binding energy, the more scattering channels and hence the more background.
[1] As one moves towards infinite binding energy, the inertia of the particles involved cause that matter increasingly behaves like vacuum, a passive entity.
