TL;DR: In this paper, the potential energy of a gas atom interacting with a solid having a surface made up of single type of exposed lattice plane can be expressed as a Fourier series in the position variables in the plane parallel to the surface.

TL;DR: The theoretical basis and experimental procedures for third-derivative modulation spectroscopy, which is the same as low-field electroreflectance, are reviewed in this article, in terms of the effect of a uniform electric field on the translational symmetry of the unperturbed crystal.

TL;DR: In this article, the authors studied the behavior of the satellite peaks from copper oxides at 25°C and 400°C, and found that the height of the Cu 2p satellite peaks was lower when the temperature was raised.

TL;DR: In this paper, structural and electronic models are proposed which correlate Goldstein's LEED, Auger, photo-emission, plasmon, and desorption data for negative electron affinity (NEA) on Si(100) surfaces.

TL;DR: The surface plasmon may be regarded as the source of the image force at an external charge and of dispersion forces between solids as mentioned in this paper, and some of the properties of surface plasmons in nearly free-electron solids are reviewed.

TL;DR: In this paper, a comparison of the spectra of metals and their oxides reveals large differences between the chemical shifts in Auger and photoelectron lines, and an explanation is proposed which is based upon the difference in polarization energy between the double-hole state produced by the Auger electron emission and the singlehole state which results from the photo-electron emission.

TL;DR: In this article, an average dielectric function is defined for a layer of small interacting, absorbing spheres which has the Lorentz form for either phonon or plasmon excitations.

TL;DR: In this paper, a quantum-mechanical model for the process by which an atom is excited or ionized as it is sputtered from a metal surface was developed, where the probability of excitation was given by R = (A/ΔE)2(hv/aΔ E)n, where A is the binding energy of a surface atom before sputtering, v is its average velocity after sputtering and Δ E the excitation energy.

TL;DR: In this paper, a novel method is presented for determining surface diffusion coefficients of adsorbates on single crystal planes of field emitters in terms of the time correlation function of current fluctuations.

TL;DR: In this paper, mass spectrometric measurements of desorption flux in the presence and absence of an incident atomic beam were obtained for Au and Cu atoms with the (0001) plane of graphite.

TL;DR: In this paper, the dependence of Auger intensities on deposition time for deposits which grow in layer-by-layer fashion is analyzed in terms of a simple model and it is shown that it is possible in principle to calibrate the Auger signals as a function of thickness absolutely with no prior assumption of values for sticking coefficients.

TL;DR: In this article, a systematic experimental study of Cs and Cs-H 2 adsorption on W (100) surfaces by LEED and work function measurements has been made.

TL;DR: In this article, the second and third virial coefficients of a classical monatomic adsorbate are put into a form suitable for numerical evaluation, which is accomplished by expanding the Boltzmann factors in the general expressions as Fourier series in the translational symmetry coordinates of the surface lattice.

TL;DR: Using the field emission retarding potential method, true work functions have been measured for the following monocrystalline substrates: W(110, W(111), W(112), Nb, Ni, Ni(100), Cu, Ir, Ir(110), and Ir(111).

TL;DR: In this article, an isotope effect in electron stimulated desorption of H+ and D+ has been found, in which the H+ ion yield is ≳ 100 × greater than the D+ ion yields, in agreement with theory.

TL;DR: In this paper, a number of typical transition metal borides have been studied using ESCA; for the sake of comparison, spectra have been obtained as well on aluminium borsides as on other boron compounds.

TL;DR: In this article, the authors used low energy electron diffraction (LEED), Auger electron spectroscopy (AES), mass spectroglobalization and work function measurements.

TL;DR: In this article, the authors investigated the kinetics of O2 adsorption on a clean Pt(111) surface in the temperature range 214-400°C and measured the oxygen coverage by CO titration as well as Auger electron spectroscopy both of which show the same dependence on O2 exposure.

TL;DR: In this paper, the initial stages of the oxidation of (110 and (100) chromium surfaces have been studied using low energy electron diffraction and Auger electron spectroscopy.

TL;DR: In this paper, the authors show that scattering of carriers by surface roughness may be important in the silicon inversion layer of metal-oxide-semiconductor structures, which is a direct result of the fluctuating potential caused by the imperfect interface which is only a small distance from the inversion carriers.

TL;DR: In this article, the Pt(100)-(5 × 1) surface was shown to have a work function change of approximately −0.7 V. This transformation is the result of a reorientation of the adsorbed benzene molecules.

TL;DR: In this paper, the authors present a summary of the main results obtained by a new method of calculating the electronic structure of solids and their surfaces in the tight-binding approximation, including the local density of states at atoms in the low index surfaces of fcc, hcp and bcc d-bands.

TL;DR: In this article, the results of spectral studies of adsorbed monolayers on metal surfaces are discussed with particular reference to surface roughness effects and photon-assisted charge transfer transitions between the metal-adatom complex and the conduction band of the substrate.

TL;DR: In this paper, the angular dependence of spectral intensities can be used to differentiate surface from bulk species, and a model is presented to account for the angular dependences and it is proposed that the angular dependencies can be exploited to distinguish surface from other bulk species.

TL;DR: In this article, the mass spectrum of the first atomic layer of the surface was obtained using ion scattering. But the authors did not consider the influence of thermal vibrations of surface atoms and of electronic excitation on the spectra.

TL;DR: In this paper, the shape of a cleaved surface is described by a combination of various results, including angles of inclination, the average angle, atomic step height, orientation and arrangement of steps, and average edge atom density.
