Fourier-transform analysis of normal photoelectron diffraction data for surface-structure determination.
A direct method for surface-structure determination from normal emission photoelectron diffraction (NPD) data is presented. Fourier transforms of the calculated NPD intensities yield peaks at adsorbate-substrate normal interlayer distances. Applications are demonstrated, using theoretical NPD curves for the Se/Ni system calculated by dynamical theory. These results show that interplanar spacing...
متن کاملAdsorption structure of glycine on TiO2(110): a photoelectron diffraction determination
High-resolution core-level photoemission and scanned-energy mode photoelectron diffraction (PhD) of the O 1s and N 1s states have been used to investigate the interaction of glycine with the rutile TiO2(110) surface. Whilst there is clear evidence for the presence of the zwitterion NH3CH2COO with multilayer deposition, at low coverage only the deprotonated glycinate species, NH2CH2COO is presen...
متن کاملDetermination of surface composition by X-ray photoelectron spectroscopy taking into account elastic photoelectron collisions.
It is now well known that elastic photoelectron scattering in the surface region of solids cannot be ignored in the mathematical formalism of quantitative XPS. Elastic collisions may increase or decrease the photoelectron signal intensity, depending on the experimental configuration. Consequently, it is advisable to take into account these effects in calculations of the surface composition. In ...
متن کاملUracil on Cu(110): a quantitative structure determination by energy-scanned photoelectron diffraction.
The local adsorption site of the nucleobase uracil on Cu(110) has been determined quantitatively by energy-scanned photoelectron diffraction (PhD). Qualitative inspection of the O 1s and N 1s soft x-ray photoelectron spectra, PhD modulation spectra, and O K-edge near-edge x-ray adsorption fine structure indicate that uracil bonds to the surface through its nitrogen and oxygen constituent atoms,...
