Photoelectron diffraction is the name given to phenomenon resulting from coherent interference of directly emitted component an electron wavefield, emerging atom as a result core level photoemission, with other components elastically scattered by surrounding atoms. Experimental characterization this effect provides information which can be used provide quantitative determinations structure surfaces, and particularly adsorbed species on in element-specific fashion. Since initial....
Alkanethiol self-assembled monolayer (SAM) phases on Au(111) have been assumed to involve direct S head group bonding the substrate. Using x-ray standing wave experiments, we show thiolate actually bonds gold adatoms; self-organization in these archetypal SAM systems must therefore be governed by movement of $\mathrm{Au}\mathrm{\text{\ensuremath{-}}}\mathrm{S}\mathrm{\text{\ensuremath{-}}}R$ moieties surface between two distinct local hollow sites surface. The results recent ab initio total...
The quantum wells formed by ultra-thin metallic films on appropriate substrates provide a real example of the simple undergraduate physics problem in mechanics `particle box'. Photoemission provides direct probe energy resulting quantized bound states. In this review relationship model system to well (QW) is explored, including way that exact nature boundaries can be taken into account relative through `phase accumulation model'. More detailed aspects photoemission QW states are also...
The technique of x-ray standing waves as a means structure determination is reviewed with special emphasis on its application to the investigation adsorbed atoms and molecules at well-characterized single crystal surfaces in ultra-high vacuum. Topics covered include: physical principles method underlying theory; methods detection absorption their relative merits; specific advantages photoelectron together description modified data analysis basis (required account for non-dipolar angular...
A new variant of the usual x-ray standing-wave experiment, scanning Bragg reflection in energy at normal incidence, is shown to be applicable metal crystals without special precautions being taken ensure high crystalline perfection.

The current state of understanding the structure metal/thiolate interface n-alkylthiolate 'self-assembled monolayers' (SAMs) on Cu(111), Ag(111) and Au(111) is reviewed. On Cu(111) there now clear evidence that adsorbate-induced reconstruction outermost metal layer occurs to a less atomically-dense structure, with S head-group atom bonded four-fold three-fold coordinated hollow sites, respectively, intermolecular interaction plays some role in periodicity resulting SAMs. far more...
A unique assignment of both the orientation and adsorption site formate (HCOO) on Cu(110) has been made by analysis near-edge extended x-ray-absorption fine structure. The species lies with its molecular plane perpendicular to surface, aligned along [$1\overline{1}0$] directions, top copper atoms outermost layer; oxygen almost bridge two an average Cu-O bond length 1.98\ifmmode\pm\else\textpm\fi{}0.07 \AA{}, essentially identical that in bulk formate.
Azimuthal anisotropies in the photoemission from Te $4d$ and Na $2p$ core levels have been measured for these atoms adsorbed $c(2\ifmmode\times\else\texttimes\fi{}2)$ configuration on Ni(001). The observed variations with photoelectron kinetic energy, polar angle of emission, adsorbate species indicate that this is a very promising technique surface-structure determination. Preliminary multiple-scattering calculations show encouraging agreement experiments.
