Hexagonal networks of linear imperfections in single crystals of cadmium

Abstract

The formation and properties of a type of hexagonal network in thin crystals of cadmium are described in this paper. The networks appear almost immediately after the disappearance of vacancy-type loops introduced by bombarding the crystals with negative ions in the electron microscope. They lie in basal planes and the directions of the three sets of intersecting lines are parallel to the ⟨ī1100⟩ directions in these planes. Mobile specks which are attributed to clusters of interstitial atoms have also been observed.
