Researchers discovered that crystal dislocations in antiferroelectric PbZrO3 thin films generate ordered polar antihedgehog lattices, creating a new defect-engineering approach for polar topologies.

Research offers insights into how crystal dislocations -- a common type of defect in materials -- can affect electrical and heat transport through crystals, at a microscopic, quantum mechanical level.

In the quest to optimize the efficiency of materials, attention is increasingly focused from the nanoscale to understanding how microscale defects, such as stacking faults and dislocations, affect the ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...

Researchers and industries have been using transmission electron microscopy (TEM) to study semiconductors' stacking and dislocation faults. This article considers the analysis of crystal structures.

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...

Researchers have dived down to the atomic scale to resolve every 'jiggle and wiggle' of atomic motion that underlies metal strength. Lawrence Livermore National Laboratory researchers have dived down ...
