Abstract
Careful analysis of high resolution electron micrographs of amorphous materials, making use of a simple optical simulation technique, provides a means for discriminating between ‘meaningful’ and ‘meaningless’ images, and for detecting ordered regions as small as 15 Å in the ‘meaningful’ ones. Such regions, comprising only about 100 atoms, have been directly observed in ‘amorphous’ carbon, and it is possible that they exist in a range of other ‘amorphous’ materials.
