Observing Surface Diffusion at the Atomic Levelbe observed have many similarities to the motion of macroscopic particles and approaches used in their study remain valid. It is fascinating, for example, to compare the mapping of individual colloid particle trajectories by Jean Perrin. with the atomic resolution trajectory mapping undertaken more自然环境 发表于 2025-3-27 20:06:04
Transport of Adsorbed Species: Correlations with Concentration and Step Structurent resolution for high adsorbate coverage field ion microscopy can not be employed to investigate diffusion caused by a concentration gradient or, in more general terms, by a chemical potential gradient. Unlike the random walk diffusion this process leads to a true mass transport over distances muchimpale 发表于 2025-3-27 23:46:53
Mass Transport by Surface Self-Diffusionxcept for some phenomenological approaches. There are no a priori theories of the 2-dimensional adsorption potential of metal surfaces which would be able to describe the motion of single adsorbed atoms such as observed experimentally.bibliophile 发表于 2025-3-28 06:00:07

Molecular Mobility and Two-Dimensional Transitions in Adsorbed Layerscharacter of the various fluids expected to be stable in surface films. If, for instance, 2D melting is a first order transition, one can anticipate, as in bulk matter, to observe two kinds of dense fluids. One, called a 2D liquid, is stable between a 2D triple point and a 2D critical temperature anThyroxine 发表于 2025-3-28 13:16:34
