Abstract
The intrinsic chirality of metal surfaces with kinked steps (e.g., Pt(643)) endows them with enantiospecific adsorption properties. To understand these properties quantitatively the impact of thermally-driven step wandering must be assessed. We derive a lattice-gas model of step motion on Pt(111) surfaces using diffusion barriers from density functional theory. This model is used to examine thermal fluctuations of straight and kinked steps.
