Spatiotemporal Self-Organization in a Surface Reaction: From the Atomic to the Mesoscopic Scale
作者： Christian Sachs , Michael Hildebrand , S Volkening , Joost Wintterlin , Gerhard Ertl
关键词:
摘要: Scanning tunneling microscopy data revealed the atomic processes in propagating reaction fronts that occur catalytic oxidation of hydrogen on Pt(111). The were also characterized mesoscopic length scales with respect to their velocity and width. Simulations basis a reaction-diffusion model reproduce experimental findings qualitatively well. quantitative comparison reveals limitations this traditional approach modeling spatiotemporal pattern formation nonlinear dynamics.
