“…Significant deviations from the dispersion of surface plasmons at jellium surfaces occur on the noble metal Ag [107,108,109,110], and the transition metals Hg [111] and Pd [297] (see Table IV). These deviations are mainly due to the presence in these metals of filled 4d and 5d bands, which in the case of Ag yields an anomalous positive and strongly crystal-face dependent dispersion.…”

“…However, first-principles calculations of the surfaceplasmon energy and linewidth dispersion of real solids have been carried out only in the case of the simple-metal prototype surfaces Mg(0001) and Al (111) [121,122]. These calculations lead to an accurate description of the measured surface-plasmon energy dispersion that is superior to that obtained in the jellium model, and they show that the band structure is of paramount importance for a correct description of the surface-plasmon linewidth.…”

“…In fact, AERPY is more suitable than electron energy-loss spectroscopy to identify the multipole surface plasmon, since the monopole surface plasmon of clean flat surfaces (which is the dominant feature in electronenergy loss spectra) is not excited by photons and thus the weaker multipole surface mode (which intersects the radiation line in the retardation regime) can be observed. A large increase in the surface photoyield was observed at ω = 0.8ω p from Al(100) [125] and Al (111) [126]. Recently, the surface electronic structure and optical response of Ag has been studied using this technique [127].…”

“…Significant deviations from the dispersion of surface plasmons at jellium surfaces occur on Ag [107,108,109,110] and Hg [111], due to the presence of filled 4d and 5d bands, respectively, which in the case of Ag yields an anomalous positive dispersion. In order to describe the observed features of Ag surface plasmons, various simplified models for the screening of d electrons have been developed [112,113,114,115,116].…”

Collective electronic excitations at metal surfaces are well known to play a key role in a wide spectrum of science, ranging from physics and materials science to biology. Here we focus on a theoretical description of the many-body dynamical electronic response of solids, which underlines the existence of various collective electronic excitations at metal surfaces, such as the conventional surface plasmon, multipole plasmons, and the recently predicted acoustic surface plasmon. We also review existing calculations, experimental measurements, and applications.

“…[1][2][3][4][5][6][7] The surface photoeffect is closely related to the excitation and the subsequent decay of the multiple surface plasmons, or multipole mode. [8][9][10][11][12][13] This mechanism of the enhancement of the surface photoemission is widely recognized and has been reported for clean surfaces and thin films of simple metals. 3,11,14,15 The mapping of the bulk band structure, using photoemission techniques, 7,[16][17][18] can be facilitated by enhanced cross section ͑and therefore more intense peaks in the photoemission spectra͒ through the Coster-Kronig resonant optical transitions, as allowed by the photoemission selection rules.…”

"Interplay between plasmons and the band structure for the Mo(112) surface" (2001). Peter Dowben Publications. 25. http://digitalcommons.unl.edu/physicsdowben/25 Interplay between plasmons and the band structure for the Mo"112… surface Recent photoemission and inverse photoemission results for the Mo͑112͒ surface are discussed in the framework of the calculated band structure. For the Mo͑112͒ surface, the main photoemission features combine contributions from both the surface and the bulk. Except for those photon energies near to excitations of the bulk and multipole surface plasmons, the comparison of the bulk band structure, along the k points normal to the surface, shows a good agreement with photoemission spectra in the position of the critical points. The dominant surface states at ⌫ are found to have the a 1 symmetry, while the band along ⌫ -Ȳ at about 0.8 eV binding energy is found to be odd with respect to the ⌫ -X mirror plane. The surface-induced enhancement of photoemission-the surface photoeffect-is indicated and is shown to be responsible for dramatic changes in the spectra when the photon energy falls into the region of the multipole surface plasmons.

Aluminium–aluminiumoxide–silver tunnel junctions allow to measure light emission by hot electrons and internal photoemission. Adsorption of potassium or oxygen on the silver electrode increases or quenches the light emission considerably. The light intensity increases at negative surface charge on the silver electrode and is suppressed at positive surface charge. Surprisingly, the light emission by hot electrons within the optical skin depth is negligible. The observed intensity is assigned to electron–photon coupling at the surface, especially to inverse photoemission by hot electrons via the time inverted threshold effect postulated by A. Liebsch. This is not in contradiction to time resolved two photon photoemission experiments. Internal photoemission experiments corroborate this interpretation.
