Further Applications of Kikuchi Diffraction Patterns; Kikuchi Maps

Abstract

Composite Kikuchi electron diffraction patterns have been obtained which map out reciprocal space for silicon over the 〈001–011–111〉 stereographic triangle. These maps enable unknown diffraction patterns to be quickly solved even when they do not contain any Kikuchi poles. Unlike spot patterns, the Kikuchi patterns and maps uniquely represent the crystal symmetry. Some applications of these maps in crystallographic and electron microscopy investigations are discussed.
