Cuprous and cupric oxides can be distinguished in the photoelectron Cu 2p spectra, since cupric compounds show two strong shake-up peaks located approximately 10eV above the principal Cu 2p3/2 peak.
It is important to note that these contaminants are not observed with other surface techniques such as scanning electron microscopy, where chemistry is measured at a micrometer scale two or three orders of magnitude deeper into the surface than what is probed by X-ray photoelectron spectroscopy.
Factoring in both the positional dependence of the effciency and the beta-decay spectrum of the electrons, we obtain a detection effciency of (48 [+ or -] 6) % when photomultiplier tube (PMT) threshold levels are set to three or more photoelectrons (see Ref.
