“…It is not possible to derive an accurate quantitative estimate of the extent of the relaxation without a more detailed assessment of the relative intensity contributions from the bulk and surface. The value of 20 ]~ corresponds to a relaxation penetrating not more than a few unit cells into the bulk grain and is in good agreement with the result of Dosch et al (1991) who found that the surface relaxation in Cu3Au alloy extends to a similar depth.…”

Abstract. The temperature evolution of the displacive order parameter of hypersolvus, A1-Si disordered alkali feldspars with composition Ors1 and Or2o was measured using X-ray powder diffractometry. The monoclinic -triclinic transition shows second-order behaviour and bilinear order parameter-strain coupling. The transition temperatures are 443 K (Or31) and 750 K (Or20). Temperature evolution of the peak width, 1; of the 132 reflection was found to depend on the grain size of the sample with an anomalous increase of F at Tc in fine-grained material. This effect has been rationalised in terms of surface relaxations occuring as Tapproaches ~. No anomalous line broadening occurs in coarse-grained material.

“…Here we show that no such effects exist in coarse-grained material. In fine-grained material we find broadening of the diffraction lines which are analysed as surface generated (Houchmandzadeh et al 1991a(Houchmandzadeh et al , b, 1992Dosch et al 1991). This is the first time that surface-related effects have been observed in feldspars.…”

“…[ 9 1 Figure 7 demonstrates that even fora relatively shallow quench (to Tc-5 deg.) only two minutes is required for surface order to develop, in sharp contrast to related bulk measurements which take hoMur to occur [10][11][12][13]. Our work forms a nice complement to depth dependent evanescent wave x-ray scattering experiments [31.…”

“…Also, the surface preparation and properties of the Au(111) herringbone reconstruction 22,23 as well as the Cu 3 Au(100)-c(2x2) surface reconstruction [24][25][26] are well documented. The annealing temperature of the Au crystal was set to 600°C in order to obtain the herringbone surface reconstruction.…”

Influence of elastic scattering on the measurement of core-level binding energy dispersion in X-ray photoemission spectroscopy

et al. 2011

In the light of recent measurements of the C 1s core level dispersion in graphene [Nat. Phys. 6, 345 (2010)], we explore the interplay between the elastic scattering of photoelectrons and the surface core level shifts with regard to the determination of core level binding energies in Au (111) and Cu3Au(100). We find that an artificial shift is created in the binding energies of the Au 4f core levels, that exhibits a dependence on the emission angle, as well as on the spectral intensity of the core level emission itself. Using a simple model, we are able to reproduce the angular dependence of the shift and relate it to the anisotropy in the electron emission from the bulk layers. Our results demonstrate that interpretation of variation of the binding energy of core-levels should be conducted with great care and must take into account the possible influence of artificial shifts induced by elastic scattering.
