www.wellesley.eduX-ray photoelectron spectroscopy (XPS) (Chapter 11), another core-level electron spectroscopy. Auger electron spectroscopy has a depth resolution of 5–25 Å, and can be used, with simultaneous ion sputtering, for depth profiling. With a lateral resolution (< 100 Å) that is significantly better than
X-ray Photoelectron Spectroscopy
assets.thermofisher.comXray photoelectron spectroscopy (XPS) is one of the foremost tools for studying this surface chemistry. In its simplest form, XPS involves shining Xrays onto a material to knock electrons from the surface atoms. By counting these ejected electrons and measuring their energy, it is possible to

Figure 3.2: A depiction of photoelectric absorption The photoelectric absorption interaction is the ideal interaction for gamma-ray spectroscopy. The photoelectron carries away most of the gamma-ray energy and then an X-ray or Auger electron carries away the remaining kinetic ...
