A particularly useful variety of UPS is angle-resolved photoelectron spectroscopy (ARPES), also called angle-resolved ultraviolet photoelectron spectroscopy (ARUPS) [, 62]. In this technique, measurements are made of the valence band photoelectrons emitted into a small angle as the electron emission angle or photon energy is varied. This allows for the simultaneous determination of the kinetic energy and momentum of the photoelectrons with respect to the two-dimensional surface Brillouin zone. From this information, the electronic band structure of a single-crystal material can be experimentally determined. [Pg.308]

From the large number of experimental methods employed currently in the analysis of surfaces (see, e.g., Morrison (1977) and Blakely (1975)), X-ray electron spectroscopy (XES), angle-resolved photoelectron spectroscopy (ARPES) and Auger electron spectroscopy (AES) are the ones which are most widely used for the study of the electronic states of the external layers of refractory phases. Their basic ideas and technical details are described in a number of monographs, see for example Nemoshkalenko et al (1976), Gallon (1981) and Briggs and Sinha (1987). [Pg.197]

Electronic spectra of surfaces can give information about what species are present and their valence states. X-ray photoelectron spectroscopy (XPS) and its variant, ESC A, are commonly used. Figure VIII-11 shows the application to an A1 surface and Fig. XVIII-6, to the more complicated case of Mo supported on TiOi [37] Fig. XVIII-7 shows the detection of photochemically produced Br atoms on Pt(lll) [38]. Other spectroscopies that bear on the chemical state of adsorbed species include (see Table VIII-1) photoelectron spectroscopy (PES) [39-41], angle resolved PES or ARPES [42], and Auger electron spectroscopy (AES) [43-47]. Spectroscopic detection of adsorbed hydrogen is difficult, and... [Pg.690]

Though a typical XPS detector collects all emitted photons, regardless of their ejection angles, it should be noted that angle-resolved XPS (ARPES) and UPS (ARUPS) may also be carried out. By detecting photoelectrons emitted from a surface at different emission angles, one obtains the energy of the electrons as a function... [Pg.400]
