Ultrahigh resolution electron microscopy of the surface structure of (110) Ag₂O

Abstract

An ultrahigh resolution transmission electron microscope and diffraction investigation of the residual oxidized silver on the surface of (111) Au films has shown that it is possible to resolve a monolayer coverage of silver atoms and the atomic structure of crystalline Ag2O surfaces. Localized patches often under 100 Å in lateral extent show a reoriented (110) oxide which often exhibits a (2 × 1) surface superstructure. The structure of various different layer coverages has been analyzed from the high resolution micrographs via digital image processing and model building to interpret surface morphology. © 1984.
