Auger electron diffraction

As the table shows, a host of other teclmiques have contributed a dozen or fewer results each. It is seen that diffraction teclmiques have been very prominent in the field the major diffraction methods have been LEED, PD, SEXAFS, XSW, XRD, while others have contributed less, such as NEXAFS, RHEED, low-energy position diffraction (LEPD), high-resolution electron energy loss spectroscopy (HREELS), medium-energy electron diffraction (MEED), Auger electron diffraction (AED), SEELFS, TED and atom diffraction (AD). 

Auger Electron Diffraction, AED, is an exact analogy to XPD, providing basically the same information. Instead of measuring the angular distribution of the ejected photoelectrons one uses the Auger electrons (Chapter 5). 

In Fig. 15a, O atoms would move to the right and Ti atoms to the left. The net effect of these displacement is to increase the effective coordination of the 5-fold coordinated Ti atoms [109]. To my knowledge, no experimental data on relaxations of the TiO2(100)(lxl) surface exist. X-ray photoelectron and Auger electron diffraction were performed but are insensitive to the details of the surface structure [111].

Core-level photoelectrons, and likewise Auger electrons, emanate from well-localized sources represented by the atomic sites of a specific elemental species. The outgoing spherical particle waves are subsequently scattered and dif acted by the neighboring atoms. When measured from a single-crystaUine sample, the resulting diffraction patterns of all these sources add up to form highly anisotropic XPD or Auger electron diffraction (AED) patterns. They carry a wealth of information on the atomic environment in which the emitter atoms are embedded [60, 61).
