Charge redistribution in ion-beam-mixed PdAg alloys

Alloying and surface composition of model Pd–Ag films synthesized by electroless deposition

“…From this figure, it is clear that as the Ag concentration is increased there is a monotonous shift toward the higher binding energy of the Ag 3d 5/2 core-level peak. Chae et al [22] reported a study of electronic structure in ion-beam-mixed PdAg alloys and found that the Ag 3d 5/2 core-level generally shifts to a lower binding energy for samples with higher palladium composition. The redistribution of the valence electrons associated with the change of the chemical bond leads to a change of energies of the core levels of atoms participating in the bond.…”

Quantitative description of short-range order and its influence on the electronic structure in Ag-Pd alloys

“…Only the respective ordered structures -L1 1 and L1 + 1 -had the lowest total energies. Finally, the calculated DOS at c = 0.25, 0.5 and 0.75 were also compared with the PES measurements of Norris and Nilsson [36], Hüfner et al [37,38], Chae et al [39] and Traditi et al [40]. In general, the experimental spectra agree best with the DOS of the random (α 1 = 0) or the ordering (α 1 < 0) cases, while the clustering features (α 1 > 0) are less probable.…”
