Zusammenfassung:
Edges and steps have been identified as the locations of surface (O2) and subsurface oxygen atoms (O1) on silver particles by means of DTF calculations and aberration-corrected transmission electron microscopy. The experemental technique allows surface features, such as terraces, steps, and edges, to be clearly imaged by eliminating the Fresnel fringes.
