Electron Microscopy of Crystal Lattices : an Anomalous Effect

Nature volume 189, pages 564–565 (1961)Cite this article

Abstract

AN explanation of intensity modulations in electron micrographs of crystal lattices1 has recently been given by Labaw2, and Hashimoto, Naiki and Mannami3 have published a theoretical interpretation of fringe separation modifications which occur when a Bragg extinction contour lies in the same direction as the crystal ‘lattice planes’ resolved. The present communication deals with the conditions which exist when a Bragg extinction contour lies across the lattice planes in question. A theory given by Cowley and Moodie4 is used to interpret a phenomenon which has recently been observed in practice (see Fig. 1).
