We study by molecular dynamics Au-2, Cu-2 and AuCu dimers diffusion on the Au(110)(1 x 2) missing-row reconstructed surface. For all these dimers, we found two different diffusion mechanisms: concerted jump and leapfrog. The energy barriers of such mechanisms are investigated and compared with the dimers dissociation barriers. Each of the three dimers exhibits a qualitatively different behavior.

Abstract
We study by molecular dynamics Au-2, Cu-2 and AuCu dimers diffusion on the Au(110)(1 x 2) missing-row reconstructed surface. For all these dimers, we found two different diffusion mechanisms: concerted jump and leapfrog. The energy barriers of such mechanisms are investigated and compared with the dimers dissociation barriers. Each of the three dimers exhibits a qualitatively different behavior.
