Analysis of top and bottom surface structure in thin (001) Au films by high resolution transmission electron microscopy
Abstract
Using computer-generated models of the (001) surface of Au a number of image computations were performed for high energy electron diffraction to match experimental transmission electron micrographs. With a multislice dynamical electron diffraction formalism it was possible to generate images from thin films which contained one roughened surface or both top and bottom surfaces roughened. Here, it will be demonstrated that the computer generated micrographs can be used to show both bulk lattice periodicities of 2.03 Å and the surface lattice of 2.86 Å and that these features are separable in real electron micrographs under favorable imaging conditions. © 1981.
