Abstract

Abstract A molecular dynamics simulation was used to determine the effect of temperature and adatom size and energy parameters on the occurrence of the exchange mechanism in cross-channel diffusion on the Pt(110) surface. Results showed that the exchange mechanism is highly dependent on temperature, occurring readily at sufficiently high temperatures, and is dependent upon adatom size in the case of a weakly interacting adatom, but, within the limits of the study, is not so in the case of a strongly interacting adatom.
