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.
