... depth of analysis is approximately 5 nm. X-ray photoelectron spectroscopy is accomplished by flooding the sample with x-rays of a known energy (typically Mg Kα at 1253.6 eV or monochromated Al Kα at 1486.7 eV). Absorption of these x-rays by the sample atoms causes photoelectrons to be emitted...
