Cover Picture: Ultrafast Electron Crystallography of Surface Structural Dynamics with Atomic-Scale Resolution (Angew. Chem. Int. Ed. 20/2004)
Surface structural dynamics are determined with unprecedented spatial and temporal resolution by ultrafast electron crystallography. The dynamics are initiated by a femtosecond laser pulse, and transient surface structures are imaged by an ultrashort electron pulse: A diffraction snapshot is obtained at a given time, δt, and allows the real-time observation of surface structural dynamics with atomic-scale resolution. For more details see the Communication by A. H. Zewail and co-workers on page 2705 ff.
