Abstract
HIGH resolution electron microscopy has developed to such an extent that atomic scale details can now be observed: local information about atomic positions is therefore directly available1,2. In contrast, diffraction experiments (X rays, neutrons, electrons) would give statistical data averaged over the whole sample, in addition to the difficulty of phase determination in complicated structures. The electron microscope is therefore a powerful and unique tool with which to study defects in the periodic structure of a crystal. We have applied this technique to dislocations and grain boundaries in germanium, and have determined their structure on a scale of 3–4 Å.
