We analyze the in-channel diffusion of dimers and longer n-adatom chains on Au and Pt (110) (1 x 2) surfaces by molecular dynamics simulations. From our calculations it arises that, on the missing-row reconstructed surface, a novel diffusion process, called leapfrog, dominates over concerted jumps, thus becoming the most frequent diffusion mechanism.

Abstract

We analyze the in-channel diffusion of dimers and longer n-adatom chains on Au and Pt (110) (1 x 2) surfaces by molecular dynamics simulations. From our calculations it arises that, on the missing-row reconstructed surface, a novel diffusion process, called leapfrog, dominates over concerted jumps, thus becoming the most frequent diffusion mechanism.
