摘要：

(Figure Presented) Edges and steps have been identified as the locations of surface (O2) and subsurface oxygen atoms (O1) on silver particles by means of DFT calculations and aberration-corrected transmission electron microscopy. The experimental technique allows surface features, such as terraces, steps, and edges, to be clearly imaged (see picture) by eliminating the Fresnel fringes. © 2008 Wiley-VCH Verlag GmbH & Co.
