Mechanisms of self-diffusion on Pt(110)

Long jumps in surface diffusion

“…More recently, however, it has been shown in calculations that instead of making double jumps, Pt atoms can move as indicated in Fig. 4b [13,14]. The atoms jump onto the {111} facets forming the channel walls, where they can migrate rapidly; this, of course, weakened the evidence for long jumps.…”

Adsorption-Induced Step Formation

“…The numerical setup is identical to the one described in Ref. [13]. Figure 3a shows that CO molecules bond strongly to Pt atoms with a low Pt coordination number, while Pt atoms with a high coordination number bind CO more weakly.…”

Fast scanning tunnelling microscopy as a tool to understand changes on metal surfaces: from nanostructures to single atoms

“…Prefactors in both cases are of the order of 10 11 /s. Subsequent theoretical work [80][81][82] showed that adatoms on the Pt(110)-(1 2 ¥ ) surface have two possible diffusion paths. They not only diffuse directly between nearest-neighbour sites in the missingrow troughs, but they can also move by performing a metastable walk involving fcc and hcp sites on the (111) microfacets forming the side walls of the troughs.…”
