Abstract

The self-diffusion of Pt on the missing row reconstructed Pt(110) surface is discussed based on density functional calculations of activation energy barriers. Different competing diffusion mechanisms are considered and we show that several different diffusion paths along the reconstruction troughs are of relevance. The analysis leads to another interpretation of the recently observed double jumps at the Pt(110) surface. [S0163-1829(99)51732-3].
